# 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.
# Rely on autoconf to set up CDPATH properly.

dnl The advantage is that the check for each of the headers/functions/decls
dnl will be put only once into the 'configure' file. It keeps the size of
dnl the 'configure' file down, and avoids redundant output when 'configure'
dnl is run.
dnl The drawback is that the checks cannot be conditionalized. If you write
dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
dnl empty, and the check will be inserted before the body of the AC_DEFUNed
dnl function.
dnl This is like onceonly.m4, except that it uses diversions to named sections
dnl DEFAULTS and INIT_PREPARE in order to check all requested headers at once,
dnl thus reducing the size of 'configure'. Works with autoconf-2.57. The

dnl Macro to add for using GNU gettext.
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
dnl default (if it is not specified or empty) is 'no-libtool'.
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/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). If INTLSYMBOL is 'no-libtool', a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
dnl the value `$(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.
