 2073: 
 2074: dnl Macro to add for using GNU gettext.
 2075: 
 2076: dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
 2077: dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
 2078: dnl    default (if it is not specified or empty) is 'no-libtool'.
 2079: dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
 2080: dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
 2081: dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
 2082: dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
 2083: dnl    depending on --{enable,disable}-{shared,static} and on the presence of
 2084: dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
 2085: dnl    $(top_builddir)/intl/libintl.a will be created.
 2086: dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
 2087: dnl    implementations (in libc or libintl) without the ngettext() function
 2088: dnl    will be ignored.  If NEEDSYMBOL is specified and is
 2089: dnl    'need-formatstring-macros', then GNU gettext implementations that don't
 2090: dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
 2091: dnl INTLDIR is used to find the intl libraries.  If empty,
 2092: dnl    the value `$(top_builddir)/intl/' is used.
 2093: dnl
 2094: dnl The result of the configuration is one of three cases:
 2095: dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
 2096: dnl    and used.
 2097: dnl    Catalog format: GNU --> install in $(datadir)
 2098: dnl    Catalog extension: .mo after installation, .gmo in source tree
 2099: dnl 2) GNU gettext has been found in the system's C library.
 2100: dnl    Catalog format: GNU --> install in $(datadir)
 2101: dnl    Catalog extension: .mo after installation, .gmo in source tree
 2102: dnl 3) No internationalization, always use English msgid.
 2103: dnl    Catalog format: none
 2104: dnl    Catalog extension: none
 2105: dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
 2106: dnl The use of .gmo is historical (it was needed to avoid overwriting the
 2107: dnl GNU format catalogs when building on a platform with an X/Open gettext),
 2108: dnl but we keep it in order not to force irrelevant filename changes on the
 2109: dnl maintainers.
