- Subject: [patch/rfc] Enable PO files.
Hello,
http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gdb&pr=761
I went shopping for solutions and found that GCC:
- generated the catalog (instead of hard wiring it in configure.in)
- the output is put in the _build_ directory (instead of RO srcdir)
and more-or-less borrowed the code. However, GCC's code also:
- insisted on using ../intl/
I didn't borrow that - GDB will still use an installed intl/ (I'm
wondering if its time to boot intl/ out of GDB's distro).

Fix PR i18n/761.
* Makefile.in (.SUFFIXES): Add po .gmo, and .pox.
(.PHONY): Add all-po install-po, uninstall-po, clean-po,
$(PACKAGE).pot and update-po.
(all-po, .po.gmo, .po.pox, install-po, $(PACKAGE).pot)
(po/$(PACKAGE).pot, clean-po, uninstall-po, install-po)
(update-po): New rules.
(localedir): Define.
(diststuff): Add $(PACKAGE).pot and $(CATALOGS)
(GDB_CFLAGS): Update -DLOCALEDIR to use $(localedir).
(XGETTEXT, GMSGFMT, MSGMERGE, PACKAGE, CATALOGS): Define.
* configure.in: Generate CATALOGS and LINGUAS from contents of
src/gdb/po/ directory.
* configure: Re-generate.
* po/gdbtext: New file
