# We are slowly moving to checking headers with the compiler instead
# of the preproc, so that we actually learn about the usability of a
# header instead of its mere presence.  But since users are used to
# the old semantics, they check for headers in random order and
# without providing prerequisite headers.  This macro implements the
# transition phase, and should be cleaned up latter to use compilation
# only.
#
# If INCLUDES is empty, then check both via the compiler and preproc.
# If the results are different, issue a warning, but keep the preproc
# result.
#
# If INCLUDES is `-', keep only the old semantics.
#
# If INCLUDES is specified and different from `-', then use the new
# semantics only.

## Macros to define obsolete macros.  ##
## ---------------------------------- ##

# AU_DEFINE(NAME, CODE)

# Define the macro NAME so that it expand to CODE only when
# autoupdate is running.  This is achieved with traces in
# autoupdate itself, so this macro expands to nothing.
#

# AU_DEFUN(NAME, NEW-CODE, [MESSAGE])
# -----------------------------------
# Declare that the macro NAME is now obsoleted, and should be replaced
# by NEW-CODE.  Tell the user she should run autoupdate, and when
# autoupdate is run, emit MESSAGE as a warning and include it in
# the updated configure.ac file.
#
# Also define NAME as a macro which code is NEW-CODE.
#
# This allows sharing the same code for both supporting obsoleted macros,
# and to update a configure.ac.
# See the end of `autoupdate.in' for a longer description.
m4_define([AU_DEFUN],
[# This is what autoupdate's m4 run will expand.  It fires
# the warning (with _au_warn_XXX), outputs it into the
# updated configure.ac (with AC_DIAGNOSE), and then outputs
# the replacement expansion.

# This is an auxiliary macro that is also run when
# autoupdate runs m4.  It simply calls m4_warning, but
# we need a wrapper so that each warning is emitted only

# order to expand this macro's arguments, not AU_DEFUN's.
AU_DEFINE([_au_warn_$1],

# AU_ALIAS(OLD-NAME, NEW-NAME)
# ----------------------------
# The OLD-NAME is no longer used, just use NEW-NAME instead.  There is
# little difference with using AU_DEFUN but the fact there is little
# interest in running the test suite on both OLD-NAME and NEW-NAME.
# This macro makes it possible to distinguish such cases.
#
# Do not use `defn' since then autoupdate would replace an old macro
# call with the new macro body instead of the new macro call.
#
# Moreover, we have to take care that calls without parameters are
# expanded to calls without parameters, not with one empty parameter.
# This is not only an aesthetic improvement of autoupdate, it also
# matters with poorly written macros which test for $# = 0.

	mmap shared not fixed
	mmap shared fixed at somewhere currently unmapped
	mmap shared fixed at somewhere already mapped

   implemented like the infamous i386 svr4.0, and systems where the
   VM page cache was not coherent with the file system buffer cache
   like early versions of FreeBSD and possibly contemporary NetBSD.)
   For shared mappings, we should conversely verify that changes get
   propagated back to all the places they're supposed to be.

Grep wants private fixed already mapped.

   * does it exist and is it safe to write into the mmap'd area

\`configure' configures m4_ifset([AC_PACKAGE_STRING],
			[AC_PACKAGE_STRING],
			[this package]) to adapt to many kinds of systems.

Usage: $[0] [[OPTION]]... [[VAR=VALUE]]...

[To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
]AS_HELP_STRING([--prefix=PREFIX],
  [install architecture-independent files in PREFIX [$ac_default_prefix]])
AS_HELP_STRING([--exec-prefix=EPREFIX],
  [install architecture-dependent files in EPREFIX [PREFIX]])[

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]

# ---------------- #
# General checks.  #
# ---------------- #

# Up to 2.13 included, Autoconf used to provide the macro
#
#    AC_CHECK_TYPE(TYPE, DEFAULT)
#
# Since, it provides another version which fits better with the other
# AC_CHECK_ families:
#
#    AC_CHECK_TYPE(TYPE,
#		   [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
#		   [INCLUDES = DEFAULT-INCLUDES])
#
# In order to provide backward compatibility, the new scheme is
# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
# and AC_CHECK_TYPE branches to one or the other, depending upon its
# arguments.

# _AC_CHECK_TYPE_NEW_BODY
# -----------------------
# Shell function body for _AC_CHECK_TYPE_NEW.  This macro implements the
# former task of AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE
# used to grep in the headers, which, BTW, led to many problems until the
# extended regular expression was correct and did not give false positives.
# It turned out there are even portability issues with egrep...
#
# The most obvious way to check for a TYPE is just to compile a variable
# definition:
#
#	  TYPE my_var;
#
# (TYPE being the second parameter to the shell function, hence $[]2 in m4).
# Unfortunately this does not work for const qualified types in C++, where
# you need an initializer.  So you think of
#
#	  TYPE my_var = (TYPE) 0;
#
# Unfortunately, again, this is not valid for some C++ classes.
#
# Then you look for another scheme.  For instance you think of declaring
# a function which uses a parameter of type TYPE:
#
#	  int foo (TYPE param);
#
# but of course you soon realize this does not make it with K&R
# compilers.  And by no means do you want to use this:
#
#	  int foo (param)
#	    TYPE param
#	  { ; }
#
# since C++ would complain loudly.
#
# Don't even think of using a function return type, since K&R cries
# there too.  So you start thinking of declaring a *pointer* to this TYPE:
#
#	  TYPE *p;
#
# but you know fairly well that this is legal in C for aggregates which
# are unknown (TYPE = struct does-not-exist).
#
# Then you think of using sizeof to make sure the TYPE is really
# defined:
#
#	  sizeof (TYPE);
#
# That is great, but has one drawback: it succeeds when TYPE happens
# to be a variable: you'd get the size of the variable's type.
# Obviously, we must not accept a variable in place of a type name.
#
# So, to filter out the last possibility, we will require that this fail:
#
#	  sizeof ((TYPE));
#
# This evokes a syntax error when TYPE is a type, but succeeds if TYPE
# is actually a variable.
#
# Also note that we use
#
#	  if (sizeof (TYPE))
#
# to `read' sizeof (to avoid warnings), while not depending on its type
# (not necessarily size_t etc.).
#
# C++ disallows defining types inside `sizeof ()', but that's OK,
# since we don't want to consider unnamed structs to be types for C++,
# precisely because they don't work in cases like that.

# Parameterizing and creating config.status.
# Copyright (C) 1992-1996, 1998-2012 Free Software Foundation, Inc.

# Written by David MacKenzie, with help from
# Franc,ois Pinard, Karl Berry, Richard Pixley, Ian Lance Taylor,
# Roland McGrath, Noah Friedman, david d zuhn, and many others.

# This file handles about all the preparation aspects for
# `config.status': registering the configuration files, the headers,
# the links, and the commands `config.status' will run.  There is a
# little mixture though of things actually handled by `configure',
# such as running the `configure' in the sub directories.  Minor
# detail.
#
# There are two kinds of commands:
#
# COMMANDS:
#
#   They are output into `config.status' via a quoted here doc.  These
#   commands are always associated to a tag which the user can use to
#   tell `config.status' what are the commands she wants to run.
#
# INIT-CMDS:
#
#   They are output via an *unquoted* here-doc.  As a consequence $var
#   will be output as the value of VAR.  This is typically used by
#   `configure' to give `config.status' some variables it needs to run
#   the COMMANDS.  At the difference of COMMANDS, the INIT-CMDS are
#   always run.
#
#
# Honorable members of this family are AC_CONFIG_FILES,
# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS.  Bad boys
# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
# arguments.  False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS
# and AC_CONFIG_AUX_DIR.  Cousins are AC_CONFIG_COMMANDS_PRE and
# AC_CONFIG_COMMANDS_POST.

# AC_PROG_MKDIR_P
# ---------------
# Check whether `mkdir -p' is known to be thread-safe, and fall back to
# install-sh -d otherwise.
#
# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
# created by `make install' are always world readable, even if the
# installer happens to have an overly restrictive umask (e.g. 077).
# This was a mistake.  There are at least two reasons why we must not
# use `-m 0755':
#   - it causes special bits like SGID to be ignored,
#   - it may be too restrictive (some setups expect 775 directories).
#
# Do not use -m 0755 and let people choose whatever they expect by
# setting umask.
#
# We cannot accept any implementation of `mkdir' that recognizes `-p'.
# Some implementations (such as Solaris 8's) are vulnerable to race conditions:
# if a parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
# concurrently, both version can detect that a/ is missing, but only
# one can create it and the other will error out.  Consequently we
# restrict ourselves to known race-free implementations.
#
# Automake used to define mkdir_p as `mkdir -p .', in order to
# allow $(mkdir_p) to be used without argument.  As in
#   $(mkdir_p) $(somedir)
# where $(somedir) is conditionally defined.  However we don't do
# that for MKDIR_P.
#  1. before we restricted the check to GNU mkdir, `mkdir -p .' was
#     reported to fail in read-only directories.  The system where this
#     happened has been forgotten.
#  2. in practice we call $(MKDIR_P) on directories such as
#       $(MKDIR_P) "$(DESTDIR)$(somedir)"
#     and we don't want to create $(DESTDIR) if $(somedir) is empty.
#     To support the latter case, we have to write
#       test -z "$(somedir)" || $(MKDIR_P) "$(DESTDIR)$(somedir)"
#     so $(MKDIR_P) always has an argument.
#     We will have better chances of detecting a missing test if
#     $(MKDIR_P) complains about missing arguments.
#  3. $(MKDIR_P) is named after `mkdir -p' and we don't expect this
#     to accept no argument.
#  4. having something like `mkdir .' in the output is unsightly.
#
# On NextStep and OpenStep, the `mkdir' command does not
# recognize any option.  It will interpret all options as
# directories to create.

## ---------- ##

# Fortran vs. Fortran 77:
#   This file contains macros for both "Fortran 77" and "Fortran", where
# the former is the "classic" autoconf Fortran interface and is intended
# for legacy F77 codes, while the latter is intended to support newer Fortran
# dialects.  Fortran 77 uses environment variables F77, FFLAGS, and FLIBS,
# while Fortran uses FC, FCFLAGS, and FCLIBS.  For each user-callable AC_*
# macro, there is generally both an F77 and an FC version, where both versions
# share the same _AC_*_FC_* backend.  This backend macro requires that
# the appropriate language be AC_LANG_PUSH'ed, and uses _AC_LANG_ABBREV and
# _AC_LANG_PREFIX in order to name cache and environment variables, etc.

## ------------------- ##
## 0. Utility macros.  ##
## ------------------- ##

# _AC_LIST_MEMBER_IF(ELEMENT, LIST, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
# ---------------------------------------------------------------------------
#
# Processing the elements of a list is tedious in shell programming,
# as lists tend to be implemented as space delimited strings.
#
# This macro searches LIST for ELEMENT, and executes ACTION-IF-FOUND
# if ELEMENT is a member of LIST, otherwise it executes
# ACTION-IF-NOT-FOUND.

# _AC_LINKER_OPTION(LINKER-OPTIONS, SHELL-VARIABLE)
# -------------------------------------------------
#
# Specifying options to the compiler (whether it be the C, C++ or
# Fortran 77 compiler) that are meant for the linker is compiler
# dependent.  This macro lets you give options to the compiler that
# are meant for the linker in a portable, compiler-independent way.
#
# This macro take two arguments, a list of linker options that the
# compiler should pass to the linker (LINKER-OPTIONS) and the name of
# a shell variable (SHELL-VARIABLE).  The list of linker options are
# appended to the shell variable in a compiler-dependent way.
#
# For example, if the selected language is C, then this:
#
#   _AC_LINKER_OPTION([-R /usr/local/lib/foo], foo_LDFLAGS)
#
# will expand into this if the selected C compiler is gcc:
#
#   foo_LDFLAGS="-Xlinker -R -Xlinker /usr/local/lib/foo"
#
# otherwise, it will expand into this:
#
#   foo_LDFLAGS"-R /usr/local/lib/foo"
#
# You are encouraged to add support for compilers that this macro
# doesn't currently support.
# FIXME: Get rid of this macro.

# _AC_FC_LIBRARY_LDFLAGS
# ----------------------
#
# Determine the linker flags (e.g. "-L" and "-l") for the Fortran
# intrinsic and runtime libraries that are required to successfully
# link a Fortran program or shared library.  The output variable
# FLIBS/FCLIBS is set to these flags.
#
# This macro is intended to be used in those situations when it is
# necessary to mix, e.g. C++ and Fortran, source code into a single
# program or shared library.
#
# For example, if object files from a C++ and Fortran compiler must
# be linked together, then the C++ compiler/linker must be used for
# linking (since special C++-ish things need to happen at link time
# like calling global constructors, instantiating templates, enabling
# exception support, etc.).
#
# However, the Fortran intrinsic and runtime libraries must be
# linked in as well, but the C++ compiler/linker doesn't know how to
# add these Fortran libraries.  Hence, the macro
# "AC_F77_LIBRARY_LDFLAGS" was created to determine these Fortran
# libraries.
#
# This macro was packaged in its current form by Matthew D. Langston.
# However, nearly all of this macro came from the "OCTAVE_FLIBS" macro
# in "octave-2.0.13/aclocal.m4", and full credit should go to John
# W. Eaton for writing this extremely useful macro.  Thank you John.

# Detect name of dummy main routine required by the Fortran libraries,
# (if any) and define {F77,FC}_DUMMY_MAIN to this name (which should be
# used for a dummy declaration, if it is defined).  On some systems,
# linking a C program to the Fortran library does not work unless you
# supply a dummy function called something like MAIN__.
#
# Execute ACTION-IF-NOT-FOUND if no way of successfully linking a C
# program with the {F77,FC} libs is found; default to exiting with an error
# message.  Execute ACTION-IF-FOUND if a dummy routine name is needed
# and found or if it is not needed (default to defining {F77,FC}_DUMMY_MAIN
# when needed).
#
# What is technically happening is that the Fortran libraries provide
# their own main() function, which usually initializes Fortran I/O and
# similar stuff, and then calls MAIN__, which is the entry point of
# your program.  Usually, a C program will override this with its own
# main() routine, but the linker sometimes complain if you don't
# provide a dummy (never-called) MAIN__ routine anyway.
#
# Of course, programs that want to allow Fortran subroutines to do
# I/O, etcetera, should call their main routine MAIN__() (or whatever)
# instead of main().  A separate autoconf test (_AC_FC_MAIN) checks
# for the routine to use in this case (since the semantics of the test
# are slightly different).  To link to e.g. purely numerical
# libraries, this is normally not necessary, however, and most C/C++
# programs are reluctant to turn over so much control to Fortran.  =)
#
# The name variants we check for are (in order):
#   MAIN__ (g77, MAIN__ required on some systems; IRIX, MAIN__ optional)
#   MAIN_, __main (SunOS)

# -----------------
# Define DST as the definition of SRC.
# What's the difference between:
# 1. m4_copy([from], [to])
# 2. m4_define([to], [from($@)])
# Well, obviously 1 is more expensive in space.  Maybe 2 is more expensive
# in time, but because of the space cost of 1, it's not that obvious.
# Nevertheless, one huge difference is the handling of `$0'.  If `from'
# uses `$0', then with 1, `to''s `$0' is `to', while it is `from' in 2.
# The user would certainly prefer to see `to'.
#
# This definition is in effect during m4sugar initialization, when

# more powerful for all other clients to use.

# too many people forget to quote the first argument of m4_define.
#
# For instance in the following case:
#   m4_define(foo, [bar])
# then a second reading will turn into
#   m4_define(bar, [bar])
# which is certainly not what was meant.

# been included.

## ------------------------------------ ##
## 5. Additional branching constructs.  ##
## ------------------------------------ ##

# Both `m4_ifval' and `m4_ifset' tests against the empty string.  The
# difference is that `m4_ifset' is specialized on macros.
#
# In case of arguments of macros, eg. $1, it makes little difference.
# In the case of a macro `FOO', you don't want to check `m4_ifval(FOO,
# TRUE)', because if `FOO' expands with commas, there is a shifting of
# the arguments.  So you want to run `m4_ifval([FOO])', but then you just
# compare the *string* `FOO' against `', which, of course fails.
#
# So you want the variation `m4_ifset' that expects a macro name as $1.
# If this macro is both defined and defined to a non empty value, then
# it runs TRUE, etc.

# m4_ifblank(COND, [IF-BLANK], [IF-TEXT])
# m4_ifnblank(COND, [IF-TEXT], [IF-BLANK])
# ----------------------------------------
# If COND is empty, or consists only of blanks (space, tab, newline),
# then expand IF-BLANK, otherwise expand IF-TEXT.  This differs from
# m4_ifval only if COND has just whitespace, but it helps optimize in
# spite of users who mistakenly leave trailing space after what they
# thought was an empty argument:
#   macro(
#         []
#        )

# Writing one macro in terms of the other causes extra overhead, so

# _m4_cdr(ARGS...)
# ----------------
# Like m4_cdr, except include a leading comma unless only one argument
# remains.  Why?  Because comparing a large list against [] is more
# expensive in expansion time than comparing the number of arguments; so
# _m4_cdr can be used to reduce the number of arguments when it is time

# -------------------------------------------------------------------
# Similar to m4_if, except that each TEST is expanded when encountered.
# If the expansion of TESTn matches the string VALn, the result is IF-VALn.
# The result is DEFAULT if no tests passed.  This macro allows
# short-circuiting of expensive tests, where it pays to arrange quick
# filter tests to run first.
#
# For an example, consider a previous implementation of _AS_QUOTE_IFELSE:
#
#    m4_if(m4_index([$1], [\]), [-1], [$2],
#          m4_eval(m4_index([$1], [\\]) >= 0), [1], [$2],

#          [$2])
#
# Here, m4_index is computed 5 times, and m4_eval 4, even if $1 contains
# no backslash.  It is more efficient to do:

# m4_expand(ARG)
# _m4_expand(ARG)

#
# Unfortunately, due to limitations in m4, ARG must expand to
# something with balanced quotes (use quadrigraphs to get around
# this), and should not contain the unlikely delimiters -=<{( or
# )}>=-.  It is possible to have unbalanced quoted `(' or `)', as well
# as unbalanced unquoted `)'.  m4_expand can handle unterminated
# comments or dnl on the final line, at the expense of speed; it also
# aids in detecting attempts to incorrectly change the current
# diversion inside ARG.  Meanwhile, _m4_expand is faster but must be
# given a terminated expansion, and has no safety checks for
# mis-diverted text.
#
# Exploit that extra unquoted () will group unquoted commas and the
# following whitespace.  m4_bpatsubst can't handle newlines inside $1,
# and m4_substr strips quoting.  So we (ab)use m4_changequote, using
# temporary quotes to remove the delimiters that conveniently included
# the unquoted () that were added prior to the changequote.
#
# Thanks to shell case statements, too many people are prone to pass
# underquoted `)', so we try to detect that by passing a marker as a
# fourth argument; if the marker is not present, then we assume that
# we encountered an early `)', and re-expand the first argument, but
# this time with one more `(' in the second argument and in the
# open-quote delimiter.  We must also ignore the slop from the

# ----------------
# Remove one layer of quotes from each ARG, performing one level of

# Implementing `foreach' loops in m4 is much more tricky than it may
# seem.  For example, the old M4 1.4.4 manual had an incorrect example,
# which looked like this (when translated to m4sugar):
#
# | # foreach(VAR, (LIST), STMT)
# | m4_define([foreach],
# |   [m4_pushdef([$1])_foreach([$1], [$2], [$3])m4_popdef([$1])])
# | m4_define([_arg1], [$1])
# | m4_define([_foreach],
# |   [m4_if([$2], [()], ,
# |     [m4_define([$1], _arg1$2)$3[]_foreach([$1], (m4_shift$2), [$3])])])
#
# But then if you run
#
# | m4_define(a, 1)
# | m4_define(b, 2)
# | m4_define(c, 3)
# | foreach([f], [([a], [(b], [c)])], [echo f
# | ])
#
# it gives
#
#  => echo 1
#  => echo (2,3)
#
# which is not what is expected.
#
# Of course the problem is that many quotes are missing.  So you add
# plenty of quotes at random places, until you reach the expected
# result.  Alternatively, if you are a quoting wizard, you directly
# reach the following implementation (but if you really did, then
# apply to the maintenance of m4sugar!).
#
# | # foreach(VAR, (LIST), STMT)
# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
# | m4_define([_arg1], [[$1]])
# | m4_define([_foreach],
# |  [m4_if($2, [()], ,
# |    [m4_define([$1], [_arg1$2])$3[]_foreach([$1], [(m4_shift$2)], [$3])])])
#
# which this time answers
#
#  => echo a
#  => echo (b
#  => echo c)
#
# Bingo!
#
# Well, not quite.
#
# With a better look, you realize that the parens are more a pain than
# a help: since anyway you need to quote properly the list, you end up
# with always using an outermost pair of parens and an outermost pair
# of quotes.  Rejecting the parens both eases the implementation, and
# simplifies the use:
#
# | # foreach(VAR, (LIST), STMT)
# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
# | m4_define([_arg1], [$1])
# | m4_define([_foreach],
# |  [m4_if($2, [], ,
# |    [m4_define([$1], [_arg1($2)])$3[]_foreach([$1], [m4_shift($2)], [$3])])])
#
#
# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
# to improve robustness, and you come up with a nice implementation
# that doesn't require extra parentheses in the user's LIST.
#
# But wait -  now the algorithm is quadratic, because every recursion of
# the algorithm keeps the entire LIST and merely adds another m4_shift to
# the quoted text.  If the user has a lot of elements in LIST, you can
# bring the system to its knees with the memory m4 then requires, or trip
# the m4 --nesting-limit recursion factor.  The only way to avoid
# quadratic growth is ensure m4_shift is expanded prior to the recursion.
# Hence the design below.
#
# The M4 manual now includes a chapter devoted to this issue, with
# the lessons learned from m4sugar.  And still, this design is only
# optimal for M4 1.6; see foreach.m4 for yet more comments on why
# M4 1.4.x uses yet another implementation.

# m4_foreach(VARIABLE, LIST, EXPRESSION)
# --------------------------------------
#
# Expand EXPRESSION assigning each value of the LIST to VARIABLE.
# LIST should have the form `item_1, item_2, ..., item_n', i.e. the
# whole list must *quoted*.  Quote members too if you don't want them
# to be expanded.
#
# This macro is robust to active symbols:
#      | m4_define(active, [ACT, IVE])
#      | m4_foreach(Var, [active, active], [-Var-])
#     => -ACT--IVE--ACT--IVE-

#     => -ACT, IVE--ACT, IVE-
#
#      | m4_foreach(Var, [[[active]], [[active]]], [-Var-])
#     => -active--active-
#
# This macro is called frequently, so avoid extra expansions such as
# m4_ifval and dnl.  Also, since $2 might be quite large, try to use it
# as little as possible in _m4_foreach; each extra use requires that much
# more memory for expansion.  So, rather than directly compare $2 against
# [] and use m4_car/m4_cdr for recursion, we instead unbox the list (which
# requires swapping the argument order in the helper), insert an ignored
# third argument, and use m4_shift3 to detect when recursion is complete,
# at which point this looks very much like m4_map_args.

#
# This macro is robust to active symbols:
#    m4_foreach_w([Var], [ active
#    b	act\
#    ive  ], [-Var-])end
#    => -active--b--active-end

#
# Since LIST may be quite large, we want to minimize how often it
# appears in the expansion.  Rather than use m4_car/m4_cdr iteration,

# for m4_apply.  SEPARATOR is expanded, in order to allow the creation
# of a list of arguments by using a single-quoted comma as the
# separator.  For each empty sublist, m4_map_sep skips the expansion
# of MACRO and SEPARATOR, while m4_mapall_sep expands MACRO with no
# arguments.
#
# For m4_mapall_sep, merely expand the first iteration without the
# separator, then include separator as part of subsequent recursion;
# but avoid extra expansion of LIST's side-effects via a helper macro.
# For m4_map_sep, things are trickier - we don't know if the first

## 10. Defining macros with bells and whistles.  ##
## --------------------------------------------- ##

# `m4_defun' is basically `m4_define' but it equips the macro with the
# needed machinery for `m4_require'.  A macro must be m4_defun'd if
# either it is m4_require'd, or it m4_require's.
#
# Two things deserve attention and are detailed below:
#  1. Implementation of m4_require
#  2. Keeping track of the expansion stack
#
# 1. Implementation of m4_require
# ===============================
#
# Of course m4_defun calls m4_provide, so that a macro which has
# been expanded is not expanded again when m4_require'd, but the
# difficult part is the proper expansion of macros when they are
# m4_require'd.
#
# The implementation is based on three ideas, (i) using diversions to
# prepare the expansion of the macro and its dependencies (by Franc,ois
# Pinard), (ii) expand the most recently m4_require'd macros _after_
# the previous macros (by Axel Thimm), and (iii) track instances of
# provide before require (by Eric Blake).
#
#
# The first idea: why use diversions?
# -----------------------------------
#
# When a macro requires another, the other macro is expanded in new
# diversion, GROW.  When the outer macro is fully expanded, we first
# undivert the most nested diversions (GROW - 1...), and finally
# undivert GROW.  To understand why we need several diversions,
# consider the following example:
#
# | m4_defun([TEST1], [Test...m4_require([TEST2])1])
# | m4_defun([TEST2], [Test...m4_require([TEST3])2])
# | m4_defun([TEST3], [Test...3])
#
# Because m4_require is not required to be first in the outer macros, we
# must keep the expansions of the various levels of m4_require separated.
# Right before executing the epilogue of TEST1, we have:
#
#	   GROW - 2: Test...3
#	   GROW - 1: Test...2
#	   GROW:     Test...1
#	   BODY:
#
# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
# GROW into the regular flow, BODY.
#
#	   GROW - 2:
#	   GROW - 1:
#	   GROW:
#	   BODY:        Test...3; Test...2; Test...1
#
# (The semicolons are here for clarification, but of course are not
# emitted.)  This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
# implement.
#
#
# The second idea: first required first out
# -----------------------------------------
#
# The natural implementation of the idea above is buggy and produces
# very surprising results in some situations.  Let's consider the
# following example to explain the bug:
#
# | m4_defun([TEST1],  [m4_require([TEST2a])m4_require([TEST2b])])
# | m4_defun([TEST2a], [])
# | m4_defun([TEST2b], [m4_require([TEST3])])
# | m4_defun([TEST3],  [m4_require([TEST2a])])
# |
# | AC_INIT
# | TEST1
#
# The dependencies between the macros are:
#
#		 3 --- 2b
#		/        \              is m4_require'd by
#	       /          \       left -------------------- right
#	    2a ------------ 1
#
# If you strictly apply the rules given in the previous section you get:
#
#	   GROW - 2: TEST3
#	   GROW - 1: TEST2a; TEST2b
#	   GROW:     TEST1
#	   BODY:
#
# (TEST2a, although required by TEST3 is not expanded in GROW - 3
# because is has already been expanded before in GROW - 1, so it has
# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
# the stack of diversions, you get:
#
#	   GROW - 2:
#	   GROW - 1:
#	   GROW:
#	   BODY:        TEST3; TEST2a; TEST2b; TEST1
#
# i.e., TEST2a is expanded after TEST3 although the latter required the
# former.
#
# Starting from 2.50, we use an implementation provided by Axel Thimm.
# The idea is simple: the order in which macros are emitted must be the
# same as the one in which macros are expanded.  (The bug above can
# indeed be described as: a macro has been m4_provide'd before its
# dependent, but it is emitted after: the lack of correlation between
# emission and expansion order is guilty).
#
# How to do that?  You keep the stack of diversions to elaborate the
# macros, but each time a macro is fully expanded, emit it immediately.
#
# In the example above, when TEST2a is expanded, but it's epilogue is
# not run yet, you have:
#
#	   GROW - 2:
#	   GROW - 1: TEST2a
#	   GROW:     Elaboration of TEST1
#	   BODY:
#
# The epilogue of TEST2a emits it immediately:
#
#	   GROW - 2:
#	   GROW - 1:
#	   GROW:     Elaboration of TEST1
#	   BODY:     TEST2a
#
# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
# have:
#
#	   GROW - 2: TEST3
#	   GROW - 1: Elaboration of TEST2b
#	   GROW:     Elaboration of TEST1
#	   BODY:      TEST2a
#
# The epilogue of TEST3 emits it:
#
#	   GROW - 2:
#	   GROW - 1: Elaboration of TEST2b
#	   GROW:     Elaboration of TEST1
#	   BODY:     TEST2a; TEST3
#
# TEST2b is now completely expanded, and emitted:
#
#	   GROW - 2:
#	   GROW - 1:
#	   GROW:     Elaboration of TEST1
#	   BODY:     TEST2a; TEST3; TEST2b
#
# and finally, TEST1 is finished and emitted:
#
#	   GROW - 2:
#	   GROW - 1:
#	   GROW:
#	   BODY:     TEST2a; TEST3; TEST2b: TEST1
#
# The idea is simple, but the implementation is a bit involved.  If
# you are like me, you will want to see the actual functioning of this
# implementation to be convinced.  The next section gives the full
# details.
#
#
# The Axel Thimm implementation at work
# -------------------------------------
#
# We consider the macros above, and this configure.ac:
#
#	    AC_INIT
#	    TEST1
#
# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
# m4_require at hand to follow the steps.
#
# This implementation tries not to assume that the current diversion is
# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
# record the current diversion under the name _m4_divert_dump (denoted
# DUMP below for short).  This introduces an important difference with
# the previous versions of Autoconf: you cannot use m4_require if you
# are not inside an m4_defun'd macro, and especially, you cannot
# m4_require directly from the top level.
#
# We have not tried to simulate the old behavior (better yet, we
# diagnose it), because it is too dangerous: a macro m4_require'd from
# the top level is expanded before the body of `configure', i.e., before
# any other test was run.  I let you imagine the result of requiring
# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
#
# After AC_INIT was run, the current diversion is BODY.
# * AC_INIT was run
#   DUMP:                undefined
#   diversion stack:     BODY |-
#
# * TEST1 is expanded
# The prologue of TEST1 sets _m4_divert_dump, which is the diversion
# where the current elaboration will be dumped, to the current
# diversion.  It also m4_divert_push to GROW, where the full
# expansion of TEST1 and its dependencies will be elaborated.
#   DUMP:        BODY
#   BODY:        empty
#   diversions:  GROW, BODY |-
#
# * TEST1 requires TEST2a
# _m4_require_call m4_divert_pushes another temporary diversion,
# GROW - 1, and expands TEST2a in there.
#   DUMP:        BODY
#   BODY:        empty
#   GROW - 1:    TEST2a
#   diversions:  GROW - 1, GROW, BODY |-
# Then the content of the temporary diversion is moved to DUMP and the
# temporary diversion is popped.
#   DUMP:        BODY
#   BODY:        TEST2a
#   diversions:  GROW, BODY |-
#
# * TEST1 requires TEST2b
# Again, _m4_require_call pushes GROW - 1 and heads to expand TEST2b.
#   DUMP:        BODY
#   BODY:        TEST2a
#   diversions:  GROW - 1, GROW, BODY |-
#
# * TEST2b requires TEST3
# _m4_require_call pushes GROW - 2 and expands TEST3 here.
# (TEST3 requires TEST2a, but TEST2a has already been m4_provide'd, so
# nothing happens.)
#   DUMP:        BODY
#   BODY:        TEST2a
#   GROW - 2:    TEST3
#   diversions:  GROW - 2, GROW - 1, GROW, BODY |-
# Then the diversion is appended to DUMP, and popped.
#   DUMP:        BODY
#   BODY:        TEST2a; TEST3
#   diversions:  GROW - 1, GROW, BODY |-
#
# * TEST1 requires TEST2b (contd.)
# The content of TEST2b is expanded...
#   DUMP:        BODY
#   BODY:        TEST2a; TEST3
#   GROW - 1:    TEST2b,
#   diversions:  GROW - 1, GROW, BODY |-
# ... and moved to DUMP.
#   DUMP:        BODY
#   BODY:        TEST2a; TEST3; TEST2b
#   diversions:  GROW, BODY |-
#
# * TEST1 is expanded: epilogue
# TEST1's own content is in GROW...
#   DUMP:        BODY
#   BODY:        TEST2a; TEST3; TEST2b
#   GROW:        TEST1
#   diversions:  BODY |-
# ... and it's epilogue moves it to DUMP and then undefines DUMP.
#   DUMP:       undefined
#   BODY:       TEST2a; TEST3; TEST2b; TEST1
#   diversions: BODY |-
#
#
# The third idea: track macros provided before they were required
# ---------------------------------------------------------------
#
# Using just the first two ideas, Autoconf 2.50 through 2.63 still had
# a subtle bug for more than seven years.  Let's consider the
# following example to explain the bug:
#
# | m4_defun([TEST1], [1])
# | m4_defun([TEST2], [2[]m4_require([TEST1])])
# | m4_defun([TEST3], [3 TEST1 m4_require([TEST2])])
# | TEST3
#
# After the prologue of TEST3, we are collecting text in GROW with the
# intent of dumping it in BODY during the epilogue.  Next, we
# encounter the direct invocation of TEST1, which provides the macro
# in place in GROW.  From there, we encounter a requirement for TEST2,
# which must be collected in a new diversion.  While expanding TEST2,
# we encounter a requirement for TEST1, but since it has already been
# expanded, the Axel Thimm algorithm states that we can treat it as a
# no-op.  But that would lead to an end result of `2 3 1', meaning
# that we have once again output a macro (TEST2) prior to its
# requirements (TEST1).
#
# The problem can only occur if a single defun'd macro first provides,
# then later indirectly requires, the same macro.  Note that directly
# expanding then requiring a macro is okay: because the dependency was
# met, the require phase can be a no-op.  For that matter, the outer
# macro can even require two helpers, where the first helper expands
# the macro, and the second helper indirectly requires the macro.
# Out-of-order expansion is only present if the inner macro is
# required by something that will be hoisted in front of where the
# direct expansion occurred.  In other words, we must be careful not
# to warn on:
#
# | m4_defun([TEST4], [4])
# | m4_defun([TEST5], [5 TEST4 m4_require([TEST4])])
# | TEST5 => 5 4
#
# or even the more complex:
#
# | m4_defun([TEST6], [6])
# | m4_defun([TEST7], [7 TEST6])
# | m4_defun([TEST8], [8 m4_require([TEST6])])
# | m4_defun([TEST9], [9 m4_require([TEST8])])
# | m4_defun([TEST10], [10 m4_require([TEST7]) m4_require([TEST9])])
# | TEST10 => 7 6 8 9 10
#
# So, to detect whether a require was direct or indirect, m4_defun and
# m4_require track the name of the macro that caused a diversion to be
# created (using the stack _m4_diverting, coupled with an O(1) lookup
# _m4_diverting([NAME])), and m4_provide stores the name associated
# with the diversion at which a macro was provided.  A require call is
# direct if it occurs within the same diversion where the macro was
# provided, or if the diversion associated with the providing context
# has been collected.
#
# The implementation of the warning involves tracking the set of
# macros which have been provided since the start of the outermost
# defun'd macro (the set is named _m4_provide).  When starting an
# outermost macro, the set is emptied; when a macro is provided, it is
# added to the set; when require expands the body of a macro, it is
# removed from the set; and when a macro is indirectly required, the
# set is checked.  If a macro is in the set, then it has been provided
# before it was required, and we satisfy dependencies by expanding the
# macro as if it had never been provided; in the example given above,
# this means we now output `1 2 3 1'.  Meanwhile, a warning is issued
# to inform the user that her macros trigger the bug in older autoconf
# versions, and that her output file now contains redundant contents
# (and possibly new problems, if the repeated macro was not
# idempotent).  Meanwhile, macros defined by m4_defun_once instead of
# m4_defun are idempotent, avoiding any warning or duplicate output.
#
#
# 2. Keeping track of the expansion stack
# =======================================
#
# When M4 expansion goes wrong it is often extremely hard to find the
# path amongst macros that drove to the failure.  What is needed is
# the stack of macro `calls'. One could imagine that GNU M4 would
# maintain a stack of macro expansions, unfortunately it doesn't, so
# we do it by hand.  This is of course extremely costly, but the help
# this stack provides is worth it.  Nevertheless to limit the
# performance penalty this is implemented only for m4_defun'd macros,
# not for define'd macros.
#
# Each time we enter an m4_defun'd macros, we add a definition in
# _m4_expansion_stack, and when we exit the macro, we remove it (thanks
# to pushdef/popdef).  m4_stack_foreach is used to print the expansion
# stack in the rare cases when it's needed.
#
# In addition, we want to detect circular m4_require dependencies.
# Each time we expand a macro FOO we define _m4_expanding(FOO); and
# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.

# m4_expansion_stack
# ------------------
# Expands to the entire contents of the expansion stack.  The caller
# must supply a trailing newline.  This macro always prints a
# location; check whether _m4_expansion_stack is defined to filter out
# the case when no defun'd macro is in force.

## 15. Set handling.  ##
## ------------------ ##

# Autoconf likes to create arbitrarily large sets; for example, as of
# this writing, the configure.ac for coreutils tracks a set of more
# than 400 AC_SUBST.  How do we track all of these set members,
# without introducing duplicates?  We could use m4_append_uniq, with
# the set NAME residing in the contents of the macro NAME.
# Unfortunately, m4_append_uniq is quadratic for set creation, because
# it costs O(n) to search the string for each of O(n) insertions; not
# to mention that with m4 1.4.x, even using m4_append is slow, costing
# O(n) rather than O(1) per insertion.  Other set operations, not used
# by Autoconf but still possible by manipulation of the definition
# tracked in macro NAME, include O(n) deletion of one element and O(n)
# computation of set size.  Because the set is exposed to the user via
# the definition of a single macro, we cannot cache any data about the
# set without risking the cache being invalidated by the user
# redefining NAME.
#
# Can we do better?  Yes, because m4 gives us an O(1) search function
# for free: ifdef.  Additionally, even m4 1.4.x gives us an O(1)
# insert operation for free: pushdef.  But to use these, we must
# represent the set via a group of macros; to keep the set consistent,
# we must hide the set so that the user can only manipulate it through
# accessor macros.  The contents of the set are maintained through two
# access points; _m4_set([name]) is a pushdef stack of values in the
# set, useful for O(n) traversal of the set contents; while the
# existence of _m4_set([name],value) with no particular value is
# useful for O(1) querying of set membership.  And since the user
# cannot externally manipulate the set, we are free to add additional
# caching macros for other performance improvements.  Deletion can be
# O(1) per element rather than O(n), by reworking the definition of
# _m4_set([name],value) to be 0 or 1 based on current membership, and
# adding _m4_set_cleanup(name) to defer the O(n) cleanup of
# _m4_set([name]) until we have another reason to do an O(n)
# traversal.  The existence of _m4_set_cleanup(name) can then be used
# elsewhere to determine if we must dereference _m4_set([name],value),
# or assume that definition implies set membership.  Finally, size can
# be tracked in an O(1) fashion with _m4_set_size(name).
#
# The quoting in _m4_set([name],value) is chosen so that there is no
# ambiguity with a set whose name contains a comma, and so that we can
# supply the value via _m4_defn([_m4_set([name])]) without needing any
# quote manipulation.

# -----------

# Autoconf is the first client of M4sh, and for two reasons: configure
# and config.status.  Relying on AS_REQUIRE is of course fine for
# configure, but fails for config.status (which is created by
# configure).  So we need a means to force the inclusion of the
# various _AS_*_PREPARE on top of config.status.  That's basically why
# there are so many _AS_*_PREPARE below, and that's also why it is
# important not to forget some: config.status needs them.
# List any preparations that create shell functions first, then
# topologically sort the others by their dependencies.
#
# Special case: we do not need _AS_LINENO_PREPARE, because the
# parent will have substituted $LINENO for us when processing its
# own invocation of _AS_LINENO_PREPARE.
#
# Special case: the full definition of _AS_ERROR_PREPARE is not output

# positives).  Hence, we perform two tests, and coordinate with
# _AS_DETECT_EXPAND (which ensures that only the first of two LINENO
# is expanded in advance) and _AS_RUN (which sets $as_run to 'a' when
# handing the test to another shell), so that we know which test to

# AS_HELP_STRING(LHS, RHS, [INDENT-COLUMN = 26], [WRAP-COLUMN = 79])
# ------------------------------------------------------------------
#
# Format a help string so that it looks pretty when the user executes
# "script --help".  This macro takes up to four arguments, a
# "left hand side" (LHS), a "right hand side" (RHS), a decimal
# INDENT-COLUMN which is the column where wrapped lines should begin
# (the default of 26 is recommended), and a decimal WRAP-COLUMN which is
# the column where lines should wrap (the default of 79 is recommended).
# LHS is expanded, RHS is not.
#
# For backwards compatibility not documented in the manual, INDENT-COLUMN
# can also be specified as a string of white spaces, whose width
# determines the indentation column.  Using TABs in INDENT-COLUMN is not
# recommended, since screen width of TAB is not computed.
#
# The resulting string is suitable for use in other macros that require
# a help string (e.g. AC_ARG_WITH).
#
# Here is the sample string from the Autoconf manual (Node: External
# Software) which shows the proper spacing for help strings.
#
#    --with-readline         support fancy command line editing
#  ^ ^                       ^
#  | |                       |
#  | column 2                column 26
#  |
#  column 0
#
# A help string is made up of a "left hand side" (LHS) and a "right
# hand side" (RHS).  In the example above, the LHS is
# "--with-readline", while the RHS is "support fancy command line
# editing".
#
# If the LHS contains more than (INDENT-COLUMN - 3) characters, then the
# LHS is terminated with a newline so that the RHS starts on a line of its
# own beginning at INDENT-COLUMN.  In the default case, this corresponds to an
# LHS with more than 23 characters.
#
# Therefore, in the example, if the LHS were instead
# "--with-readline-blah-blah-blah", then the AS_HELP_STRING macro would
# expand into:
#
#
#    --with-readline-blah-blah-blah
#  ^ ^                       support fancy command line editing
#  | |                       ^
#  | column 2                |
#  column 0                  column 26

# AS_LITERAL_IF(EXPRESSION, IF-LITERAL, IF-NOT-LITERAL,
#               [IF-SIMPLE-REF = IF-NOT-LITERAL])
# -----------------------------------------------------
# If EXPRESSION has no shell indirections ($var or `expr`), expand
# IF-LITERAL, else IF-NOT-LITERAL.  In some cases, IF-NOT-LITERAL
# must be complex to safely deal with ``, while a simpler
# expression IF-SIMPLE-REF can be used if the indirection
# involves only shell variable expansion (as in ${varname}).
#
# EXPRESSION is treated as a literal if it results in the same
# interpretation whether it is unquoted or contained within double
# quotes, with the exception that whitespace is ignored (on the
# assumption that it will be flattened to _).  Therefore, neither `\$'
# nor `a''b' is a literal, since both backslash and single quotes have
# different quoting behavior in the two contexts; and `a*' is not a
# literal, because it has different globbing.  Note, however, that
# while `${a+b}' is neither a literal nor a simple ref, `a+b' is a
# literal.  This macro is an *approximation*: it is possible that
# there are some EXPRESSIONs which the shell would treat as literals,
# but which this macro does not recognize.
#
# Why do we reject EXPRESSION expanding with `[' or `]' as a literal?
# Because AS_TR_SH is MUCH faster if it can use m4_translit on literals
# instead of m4_bpatsubst; but m4_translit is much tougher to do safely
# if `[' is translated.  That, and file globbing matters.
#
# Note that the quadrigraph @S|@ can result in non-literals, but outright
# rejecting all @ would make AC_INIT complain on its bug report address.
#
# We used to use m4_bmatch(m4_quote($1), [[`$]], [$3], [$2]), but
# profiling shows that it is faster to use m4_translit.
#
# Because the translit is stripping quotes, it must also neutralize
# anything that might be in a macro name, as well as comments, commas,
# or unbalanced parentheses.  Valid shell variable characters and
# unambiguous literal characters are deleted (`a.b'), and remaining
# characters are normalized into `$' if they can form simple refs
# (${a}), `+' if they can potentially form literals (a+b), ``' if they
# can interfere with m4 parsing, or left alone otherwise.  If both `$'
# and `+' are left, it is treated as a complex reference (${a+b}),
# even though it could technically be a simple reference (${a}+b).
# _AS_LITERAL_IF_ only has to check for an empty string after removing
# one of the two normalized characters.
#
# Rather than expand m4_defn every time AS_LITERAL_IF is expanded, we
# inline its expansion up front.  _AS_LITERAL_IF expands to the name
# of a macro that takes three arguments: IF-SIMPLE-REF,
# IF-NOT-LITERAL, IF-LITERAL.  It also takes an optional argument of
# any additional characters to allow as literals (useful for AS_TR_SH
# and AS_TR_CPP to perform inline conversion of whitespace to _).  The
# order of the arguments allows reuse of m4_default.

# foreach-based replacements for recursive functions.
# Speeds up GNU M4 1.4.x by avoiding quadratic $@ recursion, but penalizes
# GNU M4 1.6 by requiring more memory and macro expansions.
#
# Copyright (C) 2008-2012 Free Software Foundation, Inc.

# Written by Eric Blake.

# In M4 1.4.x, every byte of $@ is rescanned.  This means that an
# algorithm on n arguments that recurses with one less argument each
# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time.  In
# M4 1.6, this was fixed so that $@ is only scanned once, then
# back-references are made to information stored about the scan.
# Thus, n iterations need only scan n arguments, for O(n) time.
# Additionally, in M4 1.4.x, recursive algorithms did not clean up
# memory very well, requiring O(n^2) memory rather than O(n) for n
# iterations.
#
# This file is designed to overcome the quadratic nature of $@
# recursion by writing a variant of m4_foreach that uses m4_for rather
# than $@ recursion to operate on the list.  This involves more macro
# expansions, but avoids the need to rescan a quadratic number of
# arguments, making these replacements very attractive for M4 1.4.x.
# On the other hand, in any version of M4, expanding additional macros
# costs additional time; therefore, in M4 1.6, where $@ recursion uses
# fewer macros, these replacements actually pessimize performance.
# Additionally, the use of $10 to mean the tenth argument violates
# POSIX; although all versions of m4 1.4.x support this meaning, a
# future m4 version may switch to take it as the first argument
# concatenated with a literal 0, so the implementations in this file
# are not future-proof.  Thus, this file is conditionally included as
# part of m4_init(), only when it is detected that M4 probably has
# quadratic behavior (ie. it lacks the macro __m4_version__).
#
# Please keep this file in sync with m4sugar.m4.

# _m4_foreach(PRE, POST, IGNORED, ARG...)
# ---------------------------------------
# Form the common basis of the m4_foreach and m4_map macros.  For each
# ARG, expand PRE[ARG]POST[].  The IGNORED argument makes recursion
# easier, and must be supplied rather than implicit.
#
# This version minimizes the number of times that $@ is evaluated by
# using m4_for to generate a boilerplate into _m4_f then passing $@ to
# that temporary macro.  Thus, the recursion is done in m4_for without
# reparsing any user input, and is not quadratic.  For an idea of how
# this works, note that m4_foreach(i,[1,2],[i]) calls
#   _m4_foreach([m4_define([i],],[)i],[],[1],[2])
# which defines _m4_f:
#   $1[$4]$2[]$1[$5]$2[]_m4_popdef([_m4_f])
# then calls _m4_f([m4_define([i],],[)i],[],[1],[2]) for a net result:

=head1 NAME

Autom4te::XFile - supply object methods for filehandles with error handling

=head1 SYNOPSIS

use Autom4te::XFile;

$fh = new Autom4te::XFile;
    $fh->open ("< file");
    # No need to check $FH: we died if open failed.
    print <$fh>;
    $fh->close;
    # No need to check the return value of close: we died if it failed.

$fh = new Autom4te::XFile "> file";
    # No need to check $FH: we died if new failed.
    print $fh "bar\n";
    $fh->close;

$fh = new Autom4te::XFile "file", "r";
    # No need to check $FH: we died if new failed.
    defined $fh
    print <$fh>;
    undef $fh;   # automatically closes the file and checks for errors.

$fh = new Autom4te::XFile "file", O_WRONLY | O_APPEND;
    # No need to check $FH: we died if new failed.
    print $fh "corge\n";

$pos = $fh->getpos;
    $fh->setpos ($pos);

undef $fh;   # automatically closes the file and checks for errors.

autoflush STDOUT 1;

=head1 DESCRIPTION

C<Autom4te::XFile> inherits from C<IO::File>.  It provides the method
C<name> returning the file name.  It provides dying versions of the
methods C<close>, C<lock> (corresponding to C<flock>), C<new>,
C<open>, C<seek>, and C<truncate>.  It also overrides the C<getline>
and C<getlines> methods to translate C<\r\n> to C<\n>.

=head2 Methods

=over

=item C<$fh = new Autom4te::XFile ([$expr, ...]>

Constructor a new XFile object.  Additional arguments
are passed to C<open>, if any.

}

=item C<$fh-E<gt>open ([$file, ...])>

Open a file, passing C<$file> and further arguments to C<IO::File::open>.
Die if opening fails.  Store the name of the file.  Use binmode for writing.

=cut

sub open
{
  my $fh = shift;
  my ($file) = @_;

# WARNING: Gross hack: $FH is a typeglob: use its hash slot to store
  # the 'name' of the file we are opening.  See the example with
  # io_socket_timeout in IO::Socket for more, and read Graham's
  # comment in IO::Handle.
  ${*$fh}{'autom4te_xfile_file'} = "$file";

# In case we're running under MSWindows, don't write with CRLF.
  # (This circumvents a bug in at least Cygwin bash where the shell
  # parsing fails on lines ending with the continuation character '\'
  # and CRLF).
  binmode $fh if $file =~ /^\s*>/;
}

=item C<$fh-E<gt>close>

Close the file, handling errors.

=cut

	unless $!;
      fatal "cannot close $file: $!";

}

=item C<$line = $fh-E<gt>getline>

Read and return a line from the file.  Ensure C<\r\n> is translated to
C<\n> on input files.

=cut

# Some native Windows/perl installations fail to translate \r\n to \n on
# input so we do that here.

=item C<$fh-E<gt>lock>

Lock the file using C<flock>.  If locking fails for reasons other than
C<flock> being unsupported, then error out if C<$ENV{'MAKEFLAGS'}> indicates
that we are spawned from a parallel C<make>.

=cut

# Unless explicitly configured otherwise, Perl implements its 'flock' with the
  # first of flock(2), fcntl(2), or lockf(3) that works.  These can fail on
  # NFS-backed files, with ENOLCK (GNU/Linux) or EOPNOTSUPP (FreeBSD); we
  # usually ignore these errors.  If $ENV{MAKEFLAGS} suggests that a parallel
  # invocation of 'make' has invoked the tool we serve, report all locking
  # failures and abort.
  #
  # On Unicos, flock(2) and fcntl(2) over NFS hang indefinitely when 'lockd' is
  # not running.  NetBSD NFS clients silently grant all locks.  We do not
  # attempt to defend against these dangers.

=item C<$fh-E<gt>seek ($position, [$whence])>

Seek file to C<$position>.  Die if seeking fails.

package Autom4te::FileUtils;

=head1 NAME

Autom4te::FileUtils - handling files

=head1 SYNOPSIS

use Autom4te::FileUtils

=head1 DESCRIPTION

This perl module provides various general purpose file handling functions.

=cut

use 5.006;
use strict;
use Exporter;
use File::stat;
use IO::File;
use Autom4te::Channels;
use Autom4te::ChannelDefs;

use vars qw (@ISA @EXPORT);

@ISA = qw (Exporter);
@EXPORT = qw (&open_quote &contents
	      &find_file &mtime
	      &update_file &up_to_date_p
	      &xsystem &xsystem_hint &xqx
	      &dir_has_case_matching_file &reset_dir_cache
	      &set_dir_cache_file);

=item C<open_quote ($file_name)>

Quote C<$file_name> for open.

=cut

# $FILE_NAME
# open_quote ($FILE_NAME)
# -----------------------
# If the string $S is a well-behaved file name, simply return it.
# If it starts with white space, prepend './', if it ends with
# white space, add '\0'.  Return the new string.
sub open_quote($)

    }

    {
      $s = "$s\0";
    }
  return $s;
}

=item C<find_file ($file_name, @include)>

Return the first path for a C<$file_name> in the C<include>s.

We match exactly the behavior of GNU M4: first look in the current
directory (which includes the case of absolute file names), and then,
if the file name is not absolute, look in C<@include>.

If the file is flagged as optional (ends with C<?>), then return undef
if absent, otherwise exit with error.

# --------------------------------

	}
    }

fatal "$file_name: no such file or directory"
    unless $optional;
  return undef;
}

=item C<mtime ($file)>

Return the mtime of C<$file>.  Missing files, or C<-> standing for
C<STDIN> or C<STDOUT> are "obsolete", i.e., as old as possible.

=cut

# $MTIME
# MTIME ($FILE)
# -------------
sub mtime ($)
{
  my ($file) = @_;

return 0
    if $file eq '-' || ! -f $file;

my $stat = stat ($file)
    or fatal "cannot stat $file: $!";

return $stat->mtime;
}

=item C<update_file ($from, $to, [$force])>

Rename C<$from> as C<$to>, preserving C<$to> timestamp if it has not
changed, unless C<$force> is true (defaults to false).  Recognize
C<$to> = C<-> standing for C<STDIN>.  C<$from> is always
removed/renamed.

	}
    }

verb "up_to_date ($file): up to date";
  return 1;
}

=item C<handle_exec_errors ($command, [$expected_exit_code = 0], [$hint])>

Display an error message for C<$command>, based on the content of
C<$?> and C<$!>.  Be quiet if the command exited normally
with C<$expected_exit_code>.  If C<$hint> is given, display that as well
if the command failed to run at all.

=cut

in verbose mode.

}

=item C<dir_has_case_matching_file ($DIRNAME, $FILE_NAME)>

Return true iff $DIR contains a file name that matches $FILE_NAME case
insensitively.

We need to be cautious on case-insensitive case-preserving file
systems (e.g. Mac OS X's HFS+).  On such systems C<-f 'Foo'> and C<-f
'foO'> answer the same thing.  Hence if a package distributes its own
F<CHANGELOG> file, but has no F<ChangeLog> file, automake would still
try to distribute F<ChangeLog> (because it thinks it exists) in
addition to F<CHANGELOG>, although it is impossible for these two
files to be in the same directory (the two file names designate the
same file).

=cut

use vars '%_directory_cache';
sub dir_has_case_matching_file ($$)
{
  # Note that print File::Spec->case_tolerant returns 0 even on MacOS
  # X (with Perl v5.8.1-RC3 at least), so do not try to shortcut this
  # function using that.

my ($dirname, $file_name) = @_;
  return 0 unless -f "$dirname/$file_name";

# The file appears to exist, however it might be a mirage if the
  # system is case insensitive.  Let's browse the directory and check
  # whether the file is really in.  We maintain a cache of directories
  # so Automake doesn't spend all its time reading the same directory
  # again and again.

package Autom4te::ChannelDefs;

use Autom4te::Channels;

=head1 NAME

Autom4te::ChannelDefs - channel definitions for Automake and helper functions

=head1 SYNOPSIS

use Autom4te::ChannelDefs;

print Autom4te::ChannelDefs::usage (), "\n";
  prog_error ($MESSAGE, [%OPTIONS]);
  error ($WHERE, $MESSAGE, [%OPTIONS]);
  error ($MESSAGE);

  verb ($MESSAGE, [%OPTIONS]);
  switch_warning ($CATEGORY);
  parse_WARNINGS ();
  parse_warnings ($OPTION, @ARGUMENT);
  Autom4te::ChannelDefs::set_strictness ($STRICTNESS_NAME);

=head1 DESCRIPTION

This package defines channels that can be used in Automake to
output diagnostics and other messages (via C<msg()>).  It also defines
some helper function to enable or disable these channels, and some
shorthand function to output on specific channels.

=cut

@ISA = qw (Exporter);
@EXPORT = qw (&prog_error &error &fatal &verb
	      &switch_warning &parse_WARNINGS &parse_warnings);

=head2 CHANNELS

The following channels can be used as the first argument of
C<Autom4te::Channel::msg>.  For some of them we list a shorthand
function that makes the code more readable.

=over 4

=item C<fatal>

Fatal errors.  Use C<&fatal> to send messages over this channel.

Autom4te::Channels - support functions for error and warning management

=head1 SYNOPSIS

use Autom4te::Channels;

# Register a channel to output warnings about unused variables.
  register_channel 'unused', type => 'warning';

# Register a channel for system errors.
  register_channel 'system', type => 'error', exit_code => 4;

# Output a message on channel 'unused'.
  msg 'unused', "$file:$line", "unused variable '$var'";

# Make the 'unused' channel silent.
  setup_channel 'unused', silent => 1;

# Turn on all channels of type 'warning'.
  setup_channel_type 'warning', silent => 0;

# Redirect all channels to push messages on a Thread::Queue using
  # the specified serialization key.
  setup_channel_queue $queue, $key;

# Output a message pending in a Thread::Queue.
  pop_channel_queue $queue;

# Treat all warnings as errors.
  $warnings_are_errors = 1;

# Exit with the greatest exit code encountered so far.
  exit $exit_code;

=head1 DESCRIPTION

This perl module provides support functions for handling diagnostic
channels in programs.  Channels can be registered to convey fatal,
error, warning, or debug messages.  Each channel has various options
(e.g. is the channel silent, should duplicate messages be removed,
etc.) that can also be overridden on a per-message basis.

=over 4

=item C<$exit_code>

The greatest exit code seen so far. C<$exit_code> is updated from
the C<exit_code> options of C<fatal> and C<error> channels.

=cut

use vars qw ($exit_code);
$exit_code = 0;

=item C<$warnings_are_errors>

Set this variable to 1 if warning messages should be treated as
errors (i.e. if they should update C<$exit_code>).

=head2 Constants

=over 4

=item C<UP_NONE>, C<UP_TEXT>, C<UP_LOC_TEXT>

Possible values for the C<uniq_part> options.  This selects the part
of the message that should be considered when filtering out duplicates.
If C<UP_LOC_TEXT> is used, the location and the explanation message
are used for filtering.  If C<UP_TEXT> is used, only the explanation
message is used (so the same message will be filtered out if it appears
at different locations).  C<UP_NONE> means that duplicate messages
should be output.

=cut

use constant UP_NONE => 0;
use constant UP_TEXT => 1;
use constant UP_LOC_TEXT => 2;

=item C<US_LOCAL>, C<US_GLOBAL>

Possible values for the C<uniq_scope> options.
Use C<US_GLOBAL> for error messages that should be printed only
once during the execution of the program, C<US_LOCAL> for message that
should be printed only once per file.  (Actually, C<Channels> does not
do this now when files are changed, it relies on you calling
C<reset_local_duplicates> when this happens.)

=cut

# possible values for uniq_scope

=head2 Options

Channels accept the options described below.  These options can be
passed as a hash to the C<register_channel>, C<setup_channel>, and C<msg>
functions.  The possible keys, with their default value are:

=over

=item C<type =E<gt> 'warning'>

The type of the channel.  One of C<'debug'>, C<'warning'>, C<'error'>, or
C<'fatal'>.  Fatal messages abort the program when they are output.
Error messages update the exit status.  Debug and warning messages are
harmless, except that warnings are treated as errors if
C<$warnings_are_errors> is set.

=item C<exit_code =E<gt> 1>

The value to update C<$exit_code> with when a fatal or error message
is emitted.  C<$exit_code> is also updated for warnings output
when C<$warnings_are_errors> is set.

=item C<file =E<gt> \*STDERR>

The file where the error should be output.

=item C<silent =E<gt> 0>

Whether the channel should be silent.  Use this do disable a
category of warning, for instance.

=item C<ordered =E<gt> 1>

Whether, with multi-threaded execution, the message should be queued
for ordered output.

=item C<uniq_part =E<gt> UP_LOC_TEXT>

The part of the message subject to duplicate filtering.  See the
documentation for the C<UP_NONE>, C<UP_TEXT>, and C<UP_LOC_TEXT>
constants above.

C<uniq_part> can also be set to an arbitrary string that will be used
instead of the message when considering duplicates.

=item C<uniq_scope =E<gt> US_LOCAL>

The scope of duplicate filtering.  See the documentation for the
C<US_LOCAL>, and C<US_GLOBAL> constants above.

=item C<header =E<gt> ''>

A string to prepend to each message emitted through this channel.
With partial messages, only the first part will have C<header>
prepended.

=item C<footer =E<gt> ''>

A string to append to each message emitted through this channel.
With partial messages, only the final part will have C<footer>
appended.

=item C<backtrace =E<gt> 0>

Die with a stack backtrace after displaying the message.

=item C<partial =E<gt> 0>

When set, indicates a partial message that should
be output along with the next message with C<partial> unset.
Several partial messages can be stacked this way.

Duplicate filtering will apply to the I<global> message resulting from
all I<partial> messages, using the options from the last (non-partial)
message.  Linking associated messages is the main reason to use this
option.

For instance the following messages

msg 'channel', 'foo:2', 'redefinition of A ...';
  msg 'channel', 'foo:1', '... A previously defined here';
  msg 'channel', 'foo:3', 'redefinition of A ...';
  msg 'channel', 'foo:1', '... A previously defined here';

will result in

foo:2: redefinition of A ...
 foo:1: ... A previously defined here
 foo:3: redefinition of A ...

where the duplicate "I<... A previously defined here>" has been
filtered out.

Linking these messages using C<partial> as follows will prevent the
fourth message to disappear.

msg 'channel', 'foo:2', 'redefinition of A ...', partial => 1;
  msg 'channel', 'foo:1', '... A previously defined here';
  msg 'channel', 'foo:3', 'redefinition of A ...', partial => 1;
  msg 'channel', 'foo:1', '... A previously defined here';

Note that because the stack of C<partial> messages is printed with the
first non-C<partial> message, most options of C<partial> messages will
be ignored.

=item C<msg ($channel, $location, $message, [%options])>

Emit a message on C<$channel>, overriding some options of the channel with
those specified in C<%options>.  Obviously C<$channel> must have been
registered with C<register_channel>.

C<$message> is the text of the message, and C<$location> is a location
associated to the message.

For instance to complain about some unused variable C<mumble>
declared at line 10 in F<foo.c>, one could do:

msg 'unused', 'foo.c:10', "unused variable 'mumble'";

If channel C<unused> is not silent (and if this message is not a duplicate),
the following would be output:

foo.c:10: unused variable 'mumble'

C<$location> can also be an instance of C<Autom4te::Location>.  In this
case, the stack of contexts will be displayed in addition.

If C<$message> contains newline characters, C<$location> is prepended
to each line.  For instance,

msg 'error', 'somewhere', "1st line\n2nd line";

becomes

somewhere: 1st line
  somewhere: 2nd line

If C<$location> is an empty string, it is replaced by the name of the
program.  Actually, if you don't use C<%options>, you can even
elide the empty C<$location>.  Thus

msg 'fatal', '', 'fatal error';
  msg 'fatal', 'fatal error';

=item C<dup_channel_setup ()>, C<drop_channel_setup ()>

Sometimes it is necessary to make temporary modifications to channels.
For instance one may want to disable a warning while processing a
particular file, and then restore the initial setup.  These two
functions make it easy: C<dup_channel_setup ()> saves a copy of the
current configuration for later restoration by
C<drop_channel_setup ()>.

You can think of this as a stack of configurations whose first entry
is the active one.  C<dup_channel_setup ()> duplicates the first
entry, while C<drop_channel_setup ()> just deletes it.

  $warnings_are_errors = pop @_saved_werrors;
}

=item C<buffer_messages (@types)>, C<flush_messages ()>

By default, when C<msg> is called, messages are processed immediately.

Sometimes it is necessary to delay the output of messages.
For instance you might want to make diagnostics before
channels have been completely configured.

After C<buffer_messages(@types)> has been called, messages sent with
C<msg> to a channel whose type is listed in C<@types> will be stored in a
list for later processing.

This backlog of messages is processed when C<flush_messages> is
called, with the current channel options (not the options in effect,
at the time of C<msg>).  So for instance, if some channel was silenced
in the meantime, messages to this channel will not be printed.

C<flush_messages> cancels the effect of C<buffer_messages>.  Following
calls to C<msg> are processed immediately as usual.

PK�����4%kZ�ɶd�=���=����INSTALLnu��[�����������Installation Instructions
*************************

Basic Installation
==================

Briefly, the shell commands './configure; make; make install' should
configure, build, and install this package.  The following
more-detailed instructions are generic; see the 'README' file for
instructions specific to this package.  Some packages provide this
'INSTALL' file but do not implement all of the features documented
below.  The lack of an optional feature in a given package is not
necessarily a bug.  More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.

The 'configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation.  It uses
those values to create a 'Makefile' in each directory of the package.
It may also create one or more '.h' files containing system-dependent
definitions.  Finally, it creates a shell script 'config.status' that
you can run in the future to recreate the current configuration, and a
file 'config.log' containing compiler output (useful mainly for
debugging 'configure').

It can also use an optional file (typically called 'config.cache'
and enabled with '--cache-file=config.cache' or simply '-C') that saves
the results of its tests to speed up reconfiguring.  Caching is
disabled by default to prevent problems with accidental use of stale
cache files.

If you need to do unusual things to compile the package, please try
to figure out how 'configure' could check whether to do them, and mail
diffs or instructions to the address given in the 'README' so they can
be considered for the next release.  If you are using the cache, and at
some point 'config.cache' contains results you don't want to keep, you
may remove or edit it.

The file 'configure.ac' (or 'configure.in') is used to create
'configure' by a program called 'autoconf'.  You need 'configure.ac' if
you want to change it or regenerate 'configure' using a newer version
of 'autoconf'.

The simplest way to compile this package is:

1. 'cd' to the directory containing the package's source code and type
     './configure' to configure the package for your system.

Running 'configure' might take a while.  While running, it prints
     some messages telling which features it is checking for.

2. Type 'make' to compile the package.

3. Optionally, type 'make check' to run any self-tests that come with
     the package, generally using the just-built uninstalled binaries.

4. Type 'make install' to install the programs and any data files and
     documentation.  When installing into a prefix owned by root, it is
     recommended that the package be configured and built as a regular
     user, and only the 'make install' phase executed with root
     privileges.

5. Optionally, type 'make installcheck' to repeat any self-tests, but
     this time using the binaries in their final installed location.
     This target does not install anything.  Running this target as a
     regular user, particularly if the prior 'make install' required
     root privileges, verifies that the installation completed
     correctly.

6. You can remove the program binaries and object files from the
     source code directory by typing 'make clean'.  To also remove the
     files that 'configure' created (so you can compile the package for
     a different kind of computer), type 'make distclean'.  There is
     also a 'make maintainer-clean' target, but that is intended mainly
     for the package's developers.  If you use it, you may have to get
     all sorts of other programs in order to regenerate files that came
     with the distribution.

7. Often, you can also type 'make uninstall' to remove the installed
     files again.  In practice, not all packages have tested that
     uninstallation works correctly, even though it is required by the
     GNU Coding Standards.

8. Some packages, particularly those that use Automake, provide `make
     distcheck', which can by used by developers to test that all other
     targets like 'make install' and 'make uninstall' work correctly.
     This target is generally not run by end users.

Compilers and Options
=====================

Some systems require unusual options for compilation or linking that
the 'configure' script does not know about.  Run './configure --help'
for details on some of the pertinent environment variables.

You can give 'configure' initial values for configuration parameters
by setting variables in the command line or in the environment.  Here
is an example:

./configure CC=c99 CFLAGS=-g LIBS=-lposix

*Note Defining Variables::, for more details.

Compiling For Multiple Architectures
====================================

You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory.  To do this, you can use GNU 'make'.  'cd' to the
directory where you want the object files and executables to go and run
the 'configure' script.  'configure' automatically checks for the
source code in the directory that 'configure' is in and in '..'.  This
is known as a "VPATH" build.

With a non-GNU 'make', it is safer to compile the package for one
architecture at a time in the source code directory.  After you have
installed the package for one architecture, use 'make distclean' before
reconfiguring for another architecture.

On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple '-arch' options to the
compiler but only a single '-arch' option to the preprocessor.  Like
this:

./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
                 CPP="gcc -E" CXXCPP="g++ -E"

This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the 'lipo' tool if you have problems.

Installation Names
==================

By default, 'make install' installs the package's commands under
'/usr/local/bin', include files under '/usr/local/include', etc.  You
can specify an installation prefix other than '/usr/local' by giving
'configure' the option '--prefix=PREFIX', where PREFIX must be an
absolute file name.

You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.  If you
pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.

In addition, if you use an unusual directory layout you can give
options like '--bindir=DIR' to specify different values for particular
kinds of files.  Run 'configure --help' for a list of the directories
you can set and what kinds of files go in them.  In general, the
default for these options is expressed in terms of '${prefix}', so that
specifying just '--prefix' will affect all of the other directory
specifications that were not explicitly provided.

The most portable way to affect installation locations is to pass the
correct locations to 'configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
'make install' command line to change installation locations without
having to reconfigure or recompile.

The first method involves providing an override variable for each
affected directory.  For example, `make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
'${prefix}'.  Any directories that were specified during 'configure',
but not in terms of '${prefix}', must each be overridden at install
time for the entire installation to be relocated.  The approach of
makefile variable overrides for each directory variable is required by
the GNU Coding Standards, and ideally causes no recompilation.
However, some platforms have known limitations with the semantics of
shared libraries that end up requiring recompilation when using this
method, particularly noticeable in packages that use GNU Libtool.

The second method involves providing the 'DESTDIR' variable.  For
example, 'make install DESTDIR=/alternate/directory' will prepend
'/alternate/directory' before all installation names.  The approach of
'DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters.  On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of '${prefix}'
at 'configure' time.

Optional Features
=================

If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving 'configure' the
option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.

Some packages pay attention to '--enable-FEATURE' options to
'configure', where FEATURE indicates an optional part of the package.
They may also pay attention to '--with-PACKAGE' options, where PACKAGE
is something like 'gnu-as' or 'x' (for the X Window System).  The
'README' should mention any '--enable-' and '--with-' options that the
package recognizes.

For packages that use the X Window System, 'configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the 'configure' options '--x-includes=DIR' and
'--x-libraries=DIR' to specify their locations.

Some packages offer the ability to configure how verbose the
execution of 'make' will be.  For these packages, running `./configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with 'make V=1'; while running `./configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with 'make V=0'.

Particular systems
==================

On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:

./configure CC="cc -Ae -D_XOPEN_SOURCE=500"

and if that doesn't work, install pre-built binaries of GCC for HP-UX.

HP-UX 'make' updates targets which have the same time stamps as
their prerequisites, which makes it generally unusable when shipped
generated files such as 'configure' are involved.  Use GNU 'make'
instead.

On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its '<wchar.h>' header file.  The option '-nodtk' can be used as
a workaround.  If GNU CC is not installed, it is therefore recommended
to try

./configure CC="cc"

and if that doesn't work, try

./configure CC="cc -nodtk"

On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
directory contains several dysfunctional programs; working variants of
these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
in your 'PATH', put it _after_ '/usr/bin'.

On Haiku, software installed for all users goes in '/boot/common',
not '/usr/local'.  It is recommended to use the following options:

./configure --prefix=/boot/common

Specifying the System Type
==========================

There may be some features 'configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on.  Usually, assuming the package is built to be run on the
_same_ architectures, 'configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
'--build=TYPE' option.  TYPE can either be a short name for the system
type, such as 'sun4', or a canonical name which has the form:

CPU-COMPANY-SYSTEM

where SYSTEM can have one of these forms:

OS
     KERNEL-OS

See the file 'config.sub' for the possible values of each field.  If
'config.sub' isn't included in this package, then this package doesn't
need to know the machine type.

If you are _building_ compiler tools for cross-compiling, you should
use the option '--target=TYPE' to select the type of system they will
produce code for.

If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with '--host=TYPE'.

Sharing Defaults
================

If you want to set default values for 'configure' scripts to share,
you can create a site shell script called 'config.site' that gives
default values for variables like 'CC', 'cache_file', and 'prefix'.
'configure' looks for 'PREFIX/share/config.site' if it exists, then
'PREFIX/etc/config.site' if it exists.  Or, you can set the
'CONFIG_SITE' environment variable to the location of the site script.
A warning: not all 'configure' scripts look for a site script.

Defining Variables
==================

Variables not defined in a site shell script can be set in the
environment passed to 'configure'.  However, some packages may run
configure again during the build, and the customized values of these
variables may be lost.  In order to avoid this problem, you should set
them in the 'configure' command line, using 'VAR=value'.  For example:

./configure CC=/usr/local2/bin/gcc

causes the specified 'gcc' to be used as the C compiler (unless it is
overridden in the site shell script).

Unfortunately, this technique does not work for 'CONFIG_SHELL' due to
an Autoconf limitation.  Until the limitation is lifted, you can use
this workaround:

CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash

'configure' Invocation
======================

'configure' recognizes the following options to control how it
operates.

'--help'
'-h'
     Print a summary of all of the options to 'configure', and exit.

'--help=short'
'--help=recursive'
     Print a summary of the options unique to this package's
     'configure', and exit.  The 'short' variant lists options used
     only in the top level, while the 'recursive' variant lists options
     also present in any nested packages.

'--version'
'-V'
     Print the version of Autoconf used to generate the 'configure'
     script, and exit.

'--cache-file=FILE'
     Enable the cache: use and save the results of the tests in FILE,
     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
     disable caching.

'--config-cache'
'-C'
     Alias for '--cache-file=config.cache'.

'--quiet'
'--silent'
'-q'
     Do not print messages saying which checks are being made.  To
     suppress all normal output, redirect it to '/dev/null' (any error
     messages will still be shown).

'--srcdir=DIR'
     Look for the package's source code in directory DIR.  Usually
     'configure' can determine that directory automatically.

'--prefix=DIR'
     Use DIR as the installation prefix.  *note Installation Names::
     for more details, including other options available for fine-tuning
     the installation locations.

'--no-create'
'-n'
     Run the configure checks, but stop before creating any output
     files.

'configure' also accepts some other, not widely useful, options.  Run
'configure --help' for more details.

# the user is lunatic enough to have a file named `dnl' (and I, for
# one, love to be brainless and stubborn sometimes), then we return a
# quoted name.
#
# Gee, we can't use simply
#
#  m4_bpatsubst(__file__, [^.*/$.*$], [[\1]])
#
# since then, since `dnl' doesn't match the pattern, it is returned
# with once quotation level less, so you lose!  And since GNU M4
# is one of the biggest junk in the whole universe wrt regexp, don't
# even think about using `?' or `\?'.  Bah, `*' will do.
# Pleeeeeeeease, Gary, provide us with dirname and ERE!
#

# rarely changes.  Be fast - only compute the dirname when necessary; for

Usage: $[0] [[OPTION]... [VARIABLE=VALUE]... [TESTS]]

Run all the tests, or the selected TESTS, given by numeric ranges, and
save a detailed log file.  Upon failure, create debugging scripts.

Do not change environment variables directly.  Instead, set them via
command line arguments.  Set \`AUTOTEST_PATH' to select the executables
to exercise.  Each relative directory is expanded as build and source
directories relative to the top level of this distribution.
E.g., from within the build directory /tmp/foo-1.0, invoking this:

$ $[0] AUTOTEST_PATH=bin

is equivalent to the following, assuming the source directory is /src/foo-1.0:

PATH=/tmp/foo-1.0/bin:/src/foo-1.0/bin:\$PATH $[0]

dnl Catching signals correctly:
dnl
dnl The first idea was: trap the signal, send it to all spawned jobs,
dnl then reset the handler and reraise the signal for ourselves.
dnl However, before exiting, ksh will then send the signal to all
dnl process group members, potentially killing the outer testsuite
dnl and/or the 'make' process driving us.
dnl So now the strategy is: trap the signal, send it to all spawned jobs,
dnl then exit the script with the right status.
dnl
dnl In order to let the jobs know about the signal, we cannot just send it
dnl to the current process group (kill $SIG 0), for the same reason as above.
dnl Also, it does not reliably stop the suite to send the signal to the
dnl spawned processes, because they might not transport it further
dnl (maybe this can be fixed?).
dnl
dnl So what we do is enable shell job control if available, which causes the
dnl shell to start each parallel task as its own shell job, thus as a new
dnl process group leader.  We then send the signal to all new process groups.

dnl Do we have job control?

# If the test suite always captured data in the file `stdout', then the

# _AT_DECIDE_TRACEABLE(COMMANDS)
# ------------------------------
# Worker for _AT_CHECK that expands to shell code.  If COMMANDS are safe to
# trace with `set -x', the shell code will evaluate to true.  Otherwise,
# the shell code will print a message stating an aspect of COMMANDS that makes
# tracing them unsafe, and evaluate to false.
#
# Tracing COMMANDS is not safe if they contain a command that spans multiple
# lines.  When the test suite user passes `-x' or `--trace', the test suite
# precedes every command with a `set -x'.  Since most tests expect a specific
# stderr, if only to confirm that it is empty, the test suite filters ^+ from
# the captured stderr before comparing with the expected stderr.  If a command
# spans multiple lines, so will its trace, but a `+' only prefixes the first
# line of that trace:
#
# $ echo 'foo
# bar'
# => stdout
# foo
# bar
# => stderr
# + foo
# bar
#
# In a subset of cases, one could filter such extended shell traces from
# stderr.  Since test commands spanning several lines are rare, I chose
# instead to simply not trace COMMANDS that could yield multiple trace lines.
# Distinguishing such COMMANDS became the task at hand.
#
# These features may cause a shell command to span multiple lines:
#
# (a) A quoted literal newline.
# Example:
#   echo foo'
#   'bar
# M4 is a hostile language for the job of parsing COMMANDS to determine whether
# each literal newline is quoted, so we simply disable tracing for all COMMANDS
# that bear literal newlines.
#
# (b) A command substitution not subject to word splitting.
# Example:
#   var=$(printf 'foo\nbar')
# Example:
#   echo "`printf 'foo\\nbar`"
# One cannot know in general the number of lines a command substitution will
# yield without executing the substituted command.  As such, we disable tracing
# for all COMMANDS containing these constructs.
#
# (c) A parameter expansion not subject to word splitting.
# Example:
#   var=foo'
#   'bar
#   echo "$var"
# Parameter expansions appear in COMMANDS with much greater frequency than do
# newlines and command substitutions, so disabling tracing for all such
# COMMANDS would much more substantially devalue `testsuite -x'.  To determine
# which parameter expansions yield multiple lines, we escape all ``', `"',
# and `\' in a copy of COMMANDS and expand that string within double quotes
# at runtime.  If the result of that expansion contains multiple lines, the
# test suite disables tracing for the command in question.
#
# This method leads the test suite to expand some parameters that the shell
# itself will never expand due to single-quotes or backslash escapes.  This is
# not a problem for `$foo' expansions, which will simply yield the empty string
# or some unrelated value.  A `${...}' expansion could actually form invalid
# shell code, however; consider `${=foo}'.  Therefore, we disable tracing for
# all COMMANDS containing `${...}'.  This affects few COMMANDS.
#
# This macro falls in a very hot path; the Autoconf test suite expands it 1640
# times as of this writing.  To give a sense of the impact of the heuristics I
# just described, the test suite preemptively disables tracing for 31 of those,
# and 268 contain parameter expansions that require runtime evaluation.  The
# balance are always safe to trace.

# -------------------------------------------------
# Worker for AT_CHECK and AT_CHECK_UNQUOTED, with COMMANDS, STDOUT, and
# STDERR pre-expanded.
#
# Implementation Details
# ----------------------
# Ideally, we would like to run
#
#    ( $at_traceon; COMMANDS >at-stdout 2> at-stderr )
#
# but we must group COMMANDS as it is not limited to a single command, and
# then the shells will save the traces in at-stderr. So we have to filter
# them out when checking stderr, and we must send them into the test suite's
# stderr to honor -x properly. Since only the first line of the trace of a
# multiline command starts with a `+', and I know of no straightforward way to
# filter out the unadorned trace lines, we disable shell tracing entirely for
# commands that could span multiple lines.
#
# Limiting COMMANDS to a single command is not good either, since then
# the user herself would use {} or (), and then we face the same problem.
#
# But then, there is no point in running
#
#   ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )
#
# instead of the simpler
#
#  ( $at_traceon; $1 ) >at-stdout 2>at-stder1
#
# Note that we truncate and append to the output files, to avoid losing
# output from multiple concurrent processes, e.g., an inner testsuite
# with parallel jobs.
