# 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.

dnl Public License, this file may be distributed as part of a program
|

dnl that contains a configuration script generated by Autoconf, under
|
||
dnl the same distribution terms as the rest of that program.
|
||
|
||
dnl This file defines some "once only" variants of standard autoconf macros.
|
||
dnl AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS
|
||
dnl AC_CHECK_FUNCS_ONCE like AC_CHECK_FUNCS
|
||
dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
|
||
dnl AC_REQUIRE([AC_HEADER_STDC]) like AC_HEADER_STDC
|
||
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 Taken from Autoconf 2.50; can be removed once we assume 2.50 or later.

|
||
|
||
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.
