Version 2.1.4, interface age 1.

Wed Dec 11 14:28:50 2002  Owen Taylor  <otaylor@redhat.com>

        * configure.in: Version 2.1.4, interface age 1.

        * m4macros/glib-gettext.m4: Major rewrite; remove leftovers
        from building intl/, prefer libintl if both libc and libintl
        have dgettext and libintl also has bind_textdomain_codeset().
        (#70627)

        * configure.in acinclude.m4: Use an include to avoid having
        to duplicate the gettext macros between glib-gettext.m4
        and acinclude.m4.

        * m4macros/glib-gettext.m4: Do some tricks so that configure.in
        can use macros under hidden names, but aclocal will still
        find them when installed.

        * m4macros/glib-gettext.m4: Add AM_GLIB_DEFINE_LOCALEDIR
        to encapsulate install location of catalog files.

        * m4macros/glib-gettext.m4 (AM_GLIB_DEFINE_LOCALEDIR):
        Fix bug where if --prefix wasn't set on the configure line,
        GLib would look for translations in NONE/share/locale.
