22dnl Macro to add for using GNU gettext.
23
24dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
25dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
26dnl default (if it is not specified or empty) is 'no-libtool'.
27dnl INTLSYMBOL should be 'external' for packages with no intl directory,
28dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
29dnl If INTLSYMBOL is 'use-libtool', then a libtool library
30dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
31dnl depending on --{enable,disable}-{shared,static} and on the presence of
32dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
33dnl $(top_builddir)/intl/libintl.a will be created.
34dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
35dnl implementations (in libc or libintl) without the ngettext() function
36dnl will be ignored. If NEEDSYMBOL is specified and is
37dnl 'need-formatstring-macros', then GNU gettext implementations that don't
38dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.

43dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
44dnl and used.
45dnl Catalog format: GNU --> install in $(datadir)
46dnl Catalog extension: .mo after installation, .gmo in source tree
47dnl 2) GNU gettext has been found in the system's C library.
48dnl Catalog format: GNU --> install in $(datadir)
49dnl Catalog extension: .mo after installation, .gmo in source tree

54dnl The use of .gmo is historical (it was needed to avoid overwriting the
55dnl GNU format catalogs when building on a platform with an X/Open gettext),
56dnl but we keep it in order not to force irrelevant filename changes on the

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_HEADER_STDC]) like AC_HEADER_STDC
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.
