Thednl 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 librarydnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,dnl depending on --{enable,disable}-{shared,static} and on the presence ofdnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static librarydnl $(top_builddir)/intl/libintl.a will be created.dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettextdnl implementations (in libc or libintl) without the ngettext() functiondnl will be ignored. If NEEDSYMBOL is specified and isdnl 'need-formatstring-macros', then GNU gettext implementations that don'tdnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.dnl INTLDIR is used to find the intl libraries. If empty,dnl the value `$(top_builddir)/intl/' is used.dnldnl The result of the configuration is one of three cases:dnl 1) GNU gettext, as included in the intl subdirectory, will be compileddnl and used.dnl Catalog format: GNU --> install in $(datadir)dnl Catalog extension: .mo after installation, .gmo in source treednl 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 treednl 3) No internationalization, always use English msgid.dnl Catalog format: nonednl Catalog extension: nonednl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.dnl The use of .gmo is historical (it was needed to avoid overwriting thednl 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 thednl maintainers.dnlAC_DEFUN([AM_GNU_GETTEXT],[dnl Argument checking.ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], ,[errprint([ERROR: invalid first argument to AM_GNU_GETTEXT])])])])])ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], ,[errprint([ERROR: invalid second argument to AM_GNU_GETTEXT])])])])define(gt_included_intl, ifelse([$1], [external], [no], [yes]))define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], []))AC_REQUIRE([AM_PO_SUBDIRS])dnlifelse(gt_included_intl, yes, [AC_REQUIRE([AM_INTL_SUBDIR])dnl])dnl Prerequisites of AC_LIB_LINKFLAGS_BODY.AC_REQUIRE([AC_LIB_PREPARE_PREFIX])AC_REQUIRE([AC_LIB_RPATH])dnl Sometimes libintl requires libiconv, so first search for libiconv.dnl Ideally we would do this search only after thednl if test "$USE_NLS" = "yes"; thendnl if test "$gt_cv_func_gnugettext_libc" != "yes"; thendnl tests.
