Create runtime-po files automatically, if possible.
* configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
* data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
does not infringe on the user's name space.
(YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
* doc/bison.texinfo (Internationalization): Revamp the English
and Texinfo syntax a bit, to try to make it clearer.
(Bison Options, Option Cross Key): Mention --print-localedir.
* m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
YYENABLE_NLS. Quote a bit more.
* runtime-po/.cvsignore: New file.
* runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
* runtime-po/Rules-quot: Remove; now created by bootstrap.
* runtime-po/quot.sed: Likewise.
* runtime-po/boldquot.sed: Likewise.
* runtime-po/en@quot.header: Likewise.
* runtime-po/en@boldquot.header: Likewise.
* runtime-po/insert-header.sin: Likewise.
* runtime-po/remove-potcdate.sin: Likewise.
* runtime-po/Makevars: Likewise.
* runtime-po/LINGUAS: Likewise.
* runtime-po/de.po: Likewise; we will rely on the translation project
to maintain this, so "bootstrap" should get it.
* src/getarg.s (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
its value.
* src/main.c (main): Bind the bison-runtime domain, too.
* data/yacc.c: Include <libintl.h> when NLS is enabled.
(YYI18N): Renamed from _. Use dgettext when NLS is enabled.
* po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
* runtime-po: New directory.
* runtime-po/Makefile.in.in: New file, copied from po/, with modified
$(DOMAIN).pot-update rule, so that old messages are never dropped.
* runtime-po/Rules-quot: New file, copied from po/.
* runtime-po/quot.sed: Likewise.
* runtime-po/boldquot.sed: Likewise.
* runtime-po/en@quot.header: Likewise.
* runtime-po/en@boldquot.header: Likewise.
* runtime-po/insert-header.sin: Likewise.
* runtime-po/remove-potcdate.sin: Likewise.
* runtime-po/Makevars: New file.
* runtime-po/POTFILES.in: New file.
* runtime-po/LINGUAS: New file.
* runtime-po/bison-runtime.pot: New file.
* runtime-po/de.po: New file.
* m4/bison.m4: New file.
* Makefile.am (SUBDIRS): Add runtime-po.
(aclocaldir, aclocal_DATA): New variables.
* configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
Define aclocaldir.
* src/getargs.c (usage): Document --print-localedir option.
(PRINT_LOCALEDIR_OPTION): New enum item.
(long_options): Add --print-localedir option.
(getargs): Handle --print-localedir option.
* doc/bison.texinfo (Bison Parser): Remove paragraph about _().
(Internationalization): New section.
Remove m4/glibc2.m4 (introduced by latest gnulib, but
we don't need it).
* lib/.cvsignore: Add dup-safer.c, fd-safer.c,
fopen-safer.c, stdio-safer.h, unistd-safer.h.
* lib/subpipe.c: Include "unistd-safer.h".
(create_subpipe): Make sure all the newly-created
file descriptors are > 2, so that diagnostics don't
get sent down them (which might cause Bison to hang, in theory).
* m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
* src/files.c (xfopen): Use fopen_safer, not fopen.
(gnulib_modules): Add xalloc-die.
Set LC_ALL=C so that file names sort consistently.
Prefer the gnulib copies of gettext.m4, glibc21.m4,
inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
uintmax_t.m4, ulonglong.m4.
(intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
po.m4 since we are now using _gl.m4 instead.
