12# If the header were sys/inttypes.h, this macro would define

14# in config.h

16# The three "///" are to pacify Sun C 5.8, which otherwise would say
17# "warning: #include of /usr/include/... may be non-portable".

20dnl Macro to add for using GNU gettext.
21
22dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
23dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
24dnl default (if it is not specified or empty) is 'no-libtool'.
25dnl INTLSYMBOL should be 'external' for packages with no intl directory,
26dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
27dnl If INTLSYMBOL is 'use-libtool', then a libtool library
28dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
29dnl depending on --{enable,disable}-{shared,static} and on the presence of
30dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
31dnl $(top_builddir)/intl/libintl.a will be created.
32dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
33dnl implementations (in libc or libintl) without the ngettext() function
34dnl will be ignored. If NEEDSYMBOL is specified and is
35dnl 'need-formatstring-macros', then GNU gettext implementations that don't
36dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
37dnl INTLDIR is used to find the intl libraries. If empty,
38dnl the value `$(top_builddir)/intl/' is used.
39dnl
40dnl The result of the configuration is one of three cases:
41dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
42dnl and used.
43dnl Catalog format: GNU --> install in $(datadir)
44dnl Catalog extension: .mo after installation, .gmo in source tree
45dnl 2) GNU gettext has been found in the system's C library.
46dnl Catalog format: GNU --> install in $(datadir)
47dnl Catalog extension: .mo after installation, .gmo in source tree
48dnl 3) No internationalization, always use English msgid.
49dnl Catalog format: none
50dnl Catalog extension: none
51dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
52dnl The use of .gmo is historical (it was needed to avoid overwriting the
53dnl GNU format catalogs when building on a platform with an X/Open gettext),
54dnl but we keep it in order not to force irrelevant filename changes on the
55dnl maintainers.

3dnl This file is free software, distributed under the terms of the GNU
4dnl General Public License. As a special exception to the GNU General

6dnl that contains a configuration script generated by Autoconf, under
7dnl the same distribution terms as the rest of that program.
8
9dnl This file defines some "once only" variants of standard autoconf macros.
10dnl AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS
11dnl AC_CHECK_FUNCS_ONCE like AC_CHECK_FUNCS
12dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
13dnl AC_REQUIRE([AC_FUNC_STRCOLL]) like AC_FUNC_STRCOLL
14dnl The advantage is that the check for each of the headers/functions/decls
15dnl will be put only once into the 'configure' file. It keeps the size of
16dnl the 'configure' file down, and avoids redundant output when 'configure'
17dnl is run.
18dnl The drawback is that the checks cannot be conditionalized. If you write
19dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
20dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
21dnl empty, and the check will be inserted before the body of the AC_DEFUNed
22dnl function.
23
24dnl This is like onceonly.m4, except that it uses diversions to named sections
25dnl DEFAULTS and INIT_PREPARE in order to check all requested headers at once,
26dnl thus reducing the size of 'configure'. Works with autoconf-2.57. The
27dnl size reduction is ca. 9%.
28
29dnl Autoconf version 2.57 or newer is recommended.

10dnl POSIX 1g it is a type of its own, but some platforms use different
11dnl types for the argument to getsockopt, getpeername, etc. So we
12dnl have to test to find something that will work.

82 reject this program, as the initializer for xlcbug is
83 not one of the forms that C requires support for.
84 However, doing the test right would require a run-time
85 test, and that would make cross-compilation harder.
86 Let us hope that IBM fixes the xlc bug, and also adds
87 support for this kind of constant expression. In the
88 meantime, this test will reject xlc, which is OK, since
89 our stdbool.h substitute should suffice. We also test
90 this with GCC, where it should work, to detect more
