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    $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl    implementations (in libc or libintl) without the ngettext() function
dnl    will be ignored.
dnl INTLDIR is used to find the intl libraries.  If empty,
dnl    the value `$(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.
