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.
shouldn't be needed according to the gettext 0.12.1 documentation
but which seem to be needed anyway: codeset.m4 glibc21.m4
intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4
lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
* src/.cvsignore: Add src-gram.c.
* tests/.cvsignore: Add atlocal.
* config/.cvsignore, m4/.cvsignore, po/.cvsignore:
Add several files that autoreconf may bring in during
bootstrap.
* m4/prereq.m4 (jm_PREREQ_ARGMATCH, jm_FUNC_ARGMATCH): New.
* lib/Makefile.am (libbison_a_SOURCES): No longer include
argmatch.c and argmatch.h, since they are AC_LIBSOURCE'd.
* lib/strcasecmp.c, lib/strncasecmp.c, lib/memcmp.c: New, from the
Coreutils 4.5.1.
* src/reader.c (get_merge_function): Use xstrdup, not strdup.
* src/files.c (skeleton_find): Remove, unused.
* m4/memcmp.m4: New, from the Coreutils 4.5.1.
* m4/prereq.m4 (jm_PREREQ_QUOTEARG): Run jm_FUNC_MEMCMP.
* src/getargs.h (enum trace_e): New.
* src/getargs.c (trace_args, trace_types, trace_argmatch): New.
(long_options, short_options): --trace/-T takes an optional
argument.
Change all the uses of trace_flag to reflect the new flags.
* tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
Strengthen `stage' portability.
* m4/stage.m4 (BISON_PREREQ_STAGE): New.
* configure.in: Use it.
Don't check for malloc.h and sys/times.h.
* src/system.h: Include them when appropriate.
* src/main.c (stage): Compile only when mallinfo, struct mallinfo,
times and struct tms are available.
