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    $(top_builddir)/intl/libintl.a will be created.
34dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
35dnl    implementations (in libc or libintl) without the ngettext() function
36dnl    will be ignored.  If NEEDSYMBOL is specified and is
37dnl    'need-formatstring-macros', then GNU gettext implementations that don't
38dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
39dnl INTLDIR is used to find the intl libraries.  If empty,
40dnl    the value `$(top_builddir)/intl/' is used.
41dnl
42dnl The result of the configuration is one of three cases:
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
50dnl 3) No internationalization, always use English msgid.
51dnl    Catalog format: none
52dnl    Catalog extension: none
53dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
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
57dnl maintainers.
