dnl This file can can be used in projects which are not available under
dnl the GNU General Public License or the GNU Library General Public
dnl License but which still want to provide support for the GNU gettext
dnl functionality.
dnl Please note that the actual code of the GNU gettext library is covered
dnl by the GNU Library General Public License, and the rest of the GNU

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.

dnl Sometimes libintl requires libiconv, so first search for libiconv.
dnl Ideally we would do this search only after the
dnl if test "$USE_NLS" = "yes"; then
dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then
dnl tests. But if configure.in invokes AM_ICONV after AM_GNU_GETTEXT
dnl the configure script would need to contain the same shell code
dnl again, outside any 'if'. There are two solutions:
dnl - Invoke AM_ICONV_LINKFLAGS_BODY here, outside any 'if'.
dnl - Control the expansions in more detail using AC_PROVIDE_IFELSE.
dnl Since AC_PROVIDE_IFELSE is only in autoconf >= 2.52 and not
dnl documented, we avoid it.
