# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# Use '""', not '<>', so that the /// cannot be confused with a C99 comment.

(Sun C 5.15 SunOS_sparc 2017/05/30).
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since the C standard prohibits extern inline functions
from calling static functions (ISO C 99 section 6.7.4.(3).
This bug is known to occur on:
OS X 10.8 and earlier; see:
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
FreeBSD; see:
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
Assume DragonFly and FreeBSD will be similar.
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
inline semantics, unless -fgnu89-inline is used. It defines a macro
__GNUC_STDC_INLINE__ to indicate this situation or a macro
__GNUC_GNU_INLINE__ to indicate the opposite situation.
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
semantics but warns, unless -fgnu89-inline is used:
warning: C99 inline functions are not supported; using GNU89
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

dnl Copyright (C) 2006-2022 Free Software Foundation, Inc.
dnl This file is free software; the Free Software Foundation
dnl gives unlimited permission to copy and/or distribute it,
dnl with or without modifications, as long as this notice is preserved.
dnl From Paul Eggert and Derek Price.
dnl Sets INCLUDE_NEXT, INCLUDE_NEXT_AS_FIRST_DIRECTIVE, PRAGMA_SYSTEM_HEADER,
dnl and PRAGMA_COLUMNS.
dnl
dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
dnl 'include' otherwise.
dnl
dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
dnl supports it in the special case that it is the first include directive in
dnl the given file, or to 'include' otherwise.
dnl
dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
dnl '#pragma GCC system_header' has the same effect as if the file was found
dnl through the include search path specified with '-isystem' options (as
dnl opposed to the search path specified with '-I' options). Namely, gcc
dnl does not warn about some things, and on some systems (Solaris and Interix)
dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
dnl of plain '__STDC__'.

# well as ideas on poisoning global variables and macros. NAMES may
# include global variables, but remember that only functions work with
# _GL_WARN_ON_USE. Typically, INCLUDES only needs to list a single
# header, but if the replacement header pulls in other headers because
# some systems declare functions in the wrong header, then INCLUDES
# should do likewise.

# in the intersection of C89 and C11 (such as printf) without

dnl Written by Bruno Haible.
dnl When the build environment ($build_os) is different from the target runtime
dnl environment ($host_os), file names may need to be converted from the build
dnl environment syntax to the target runtime environment syntax. This is
dnl because the Makefiles are executed (mostly) by build environment tools and
dnl therefore expect file names in build environment syntax, whereas the runtime
dnl expects file names in target runtime environment syntax.
dnl
dnl For example, if $build_os = cygwin and $host_os = mingw32, filenames need
dnl be converted from Cygwin syntax to native Windows syntax:
dnl /cygdrive/c/foo/bar -> C:\foo\bar
dnl /usr/local/share -> C:\cygwin64\usr\local\share
dnl
dnl gl_BUILD_TO_HOST([somedir])
dnl This macro takes as input an AC_SUBSTed variable 'somedir', which must
dnl already have its final value assigned, and produces two additional
dnl AC_SUBSTed variables 'somedir_c' and 'somedir_c_make', that designate the
dnl same file name value, just in different syntax:
dnl - somedir_c is the file name in target runtime environment syntax,
dnl as a C string (starting and ending with a double-quote,
dnl and with escaped backslashes and double-quotes in
dnl between).
dnl - somedir_c_make is the same thing, escaped for use in a Makefile.

dnl Macro to add for using GNU gettext.
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
dnl INTLSYMBOL must be one of 'external', 'use-libtool', 'here'.
dnl INTLSYMBOL should be 'external' for packages other than GNU gettext.
dnl It should be 'use-libtool' for the packages 'gettext-runtime' and
dnl 'gettext-tools'.
dnl It should be 'here' for the package 'gettext-runtime/intl'.
dnl If INTLSYMBOL is 'here', then a libtool library
dnl $(top_builddir)/libintl.la will be created (shared and/or static,
dnl depending on --{enable,disable}-{shared,static} and on the presence of
dnl AM-DISABLE-SHARED).
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
dnl the value '$(top_builddir)/intl/' is used.
dnl
dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl and used.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 3) No internationalization, always use English msgid.
dnl Catalog format: none
dnl Catalog extension: none
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
dnl maintainers.

dnl gives unlimited permission to copy and/or distribute it,
dnl with or without modifications, as long as this notice is preserved.
dnl This file is offered as-is, without any warranty.
dnl From Bruno Haible and Sam Steingold.
dnl Sets the HOST_CPU variable to the canonical name of the CPU.
dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
dnl C language ABI (application binary interface).
dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
dnl config.h.
dnl
dnl This canonical name can be used to select a particular assembly language
dnl source file that will interoperate with C code on the given host.
dnl
dnl For example:
dnl * 'i386' and 'sparc' are different canonical names, because code for i386
dnl will not run on SPARC CPUs and vice versa. They have different
dnl instruction sets.
dnl * 'sparc' and 'sparc64' are different canonical names, because code for
dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
dnl mode, but not both.
dnl * 'mips' and 'mipsn32' are different canonical names, because they use
dnl different argument passing and return conventions for C functions, and
dnl although the instruction set of 'mips' is a large subset of the
dnl instruction set of 'mipsn32'.
dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
dnl different sizes for the C types like 'int' and 'void *', and although
dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
dnl * The same canonical name is used for different endiannesses. You can
dnl determine the endianness through preprocessor symbols:
dnl - 'arm': test __ARMEL__.
dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
dnl - 'powerpc64': test __BIG_ENDIAN__ vs. __LITTLE_ENDIAN__.
dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
dnl assembly language source files use such instructions, you will
dnl need to make the distinction.
dnl - Speed of execution of the common instruction set is reasonable across
dnl the entire family of CPUs. If you have assembly language source files
dnl that are optimized for particular CPU types (like GNU gmp has), you
dnl will need to make the distinction.

# list of exported symbols of that shared object, eventually

# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.
