+dnl @synopsis AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])

+dnl

+dnl This macro _AC_DEFINEs VARNAME to the expansion of the DIR

+dnl variable, taking care of fixing up ${prefix} and such.

+dnl

+dnl VARNAME is offered as both a C preprocessor symbol, and an output

+dnl variable.

+dnl

+dnl Note that the 3 argument form is only supported with autoconf 2.13

+dnl and later (i.e. only where _AC_DEFINE supports 3 arguments).

+dnl

+dnl Examples:

+dnl

+dnl    AC_DEFINE_DIR(DATADIR, datadir)

+dnl    AC_DEFINE_DIR(PROG_PATH, bindir, [Location of installed binaries])

+dnl

+dnl @category Misc

+dnl @author Stepan Kasal <kasal@ucw.cz>

+dnl @author Andreas Schwab <schwab@suse.de>

+dnl @author Guido Draheim <guidod@gmx.de>

+dnl @author Alexandre Oliva

+dnl @version 2005-01-17

+
+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.
