* gnulib: Update to latest.
* lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
* m4/.gitignore: Regen.
* src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
Call xalloc_die on hash_insert failures.
Requested by the new __warn_unused_result__ attribute of
hash_insert.
If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
requirements for a correct m4 are stricter.
* m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
* configure.ac: Update to use AC_PROG_GNU_M4.
Reported by Eric Blake.
* HACKING (Administrivia): Make the git-merge-changelog notes more
helpful.
(Test suite): Don't say lalr1.cc is not exercised in the test suite.
(Release Procedure): Update for git and add numerous details that were
previously missing.
* Makefile.am (EXTRA_DIST): Remove Makefile.cfg and Makefile.maint.
* maint.mk (announcement): Don't list bison as a bootstrap tool so
that announcements don't claim we bootstrapped with whatever bison
happened to be in PATH. Add flex as a bootstrap tool.
* Makefile.maint: Remove, previously replaced by maint.mk.
* Makefile.cfg: Remove, and migrate settings to...
* cfg.mk: ... here for the sake of `make announcement'.
* bootstrap.conf (gnulib_modules): Add announce-gen.
* README: Say GNU Bison instead of just Bison. Suggested by Karl
Berry.
Reported by Eric Blake at
<http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.
* bootstrap.conf (gnulib_modules): Add unsetenv.
* lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
* m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
(/setenv.m4): Add.
* src/output.c (output_skeleton): For the m4 invocation, pass -dV as
the first argument because it may become position-dependent, and unset
POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
Add comments explaining these issues in more detail.
* bootstrap: Likewise.
* Makefile.cfg: Adjust to new GNUmakefile.
* README-hacking: Likewise.

2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
Bruno Haible <bruno@clisp.org>
* m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
and is a script that invokes bison. Tighten the code. Add comments.
instead of fprintf. Guard these functions with #if YYDEBUG instead of
#ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
and so that YYFPRINTF is guaranteed to be defined here.
introduced in the 2007-02-03 change. Bruno Haible reported that
the 2007-02-07 change would be dangerous in Turkish if we add a
language whose name contains "i", since "i" is not lowercase "I"
in Turkish.
* bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
* lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
* m4/.cvsignore: Remove strcase.m4.
* src/getargs.c: Revert 2007-02-07 change, as follows.
Include c-strcase.h.
(language_argmatch): Use c_strcasecmp rather than strcasecmp.
now that gnulib strcase has been fixed.
* bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
* lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
* m4/.cvsignore: Add strcase.m4.
* src/getargs.c: Revert 2007-02-03 change, as follows.
Don't include c-strcase.h.
(language_argmatch): Use strcasecmp rather than c_strcasecmp.
strcasecmp has "unspecified behavior" outside the POSIX locale,
but it works fine in practice if at least one argument is ASCII,
as is the case in Bison.
* NEWS: Mention java.
* TODO: Remove things that are done.
* bootstrap.conf: Add javacomp-script and javaexec-script.
* configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.

C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
under Other Languages.

* tests/java.at: New.
* tests/testsuite.at: Include it.
instead of passing a yylexp argument to yypull_parse, and don't
generate yypull_parse or yyparse unless %push-pull-parser is declared.
Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
* data/bison.m4 (b4_pull_if): New.
* data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
* data/push.c: Improve M4 quoting a little.
(b4_generate_macro_args, b4_parenthesize): Remove.
(yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
any time a pull parser is requested.
Don't #define this as a wrapper around yypull_parse. Instead, when
both push and pull are requested, make it a function that does that
same thing.
(yypull_parse): If there's a b4_prefix, #define this to
b4_prefix[pull_parse] when both push and pull are requested.
Don't define this as a function unless both push and pull are
requested.
Remove the yylexp argument and hard-code yylex invocation instead.
* etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
%push-parser.
* src/getargs.c (pull_parser): New global initialized to true.
* getargs.h (pull_parser): extern it.
* src/output.c (prepare): Insert pull_flag muscle.
* src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
(prologue_declaration): Set both push_parser and pull_parser = true for
%push-pull-parser. Set push_parser = true and pull_parser = false for
%push-parser.
* src/scan-gram.l: Don't accept %push_parser as an alternative to
%push-parser since there's no backward-compatibility concern here.
Scan %push-pull-parser.
* tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
instead of %push-parser.
* tests/headers.at (export YYLTYPE): Make yylex static, and don't
prototype it in the module that calls yyparse.
* tests/input.at (Torturing the Scanner): Likewise.
* tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
us a slightly cleaner distribution, and also works.
* m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
gnulib changes.
* bootstrap: Sync from coreutils, except add support for gnulib_files.
* bootstrap.conf: New file.
(gnulib_modules): Add configmake, inttypes, unistd.
(XGETTEXT_OPTIONS): Add complain, complain_at,
fatal, fatal_at, warn, warn_at, unexpected_end.
* configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
(gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
(gl_EARLY): Add.
(AM_STDBOOL_H): Remove; gl_INIT now dows this.
(gl_INIT): Add
(GNULIB_AUTOCONF_SNIPPET): Remove.
(AM_GNU_GETTEXT): Add; require formatstring macros since that's
the pickiest.
* lib/.cvsignore: Add inttypes_.h.
* lib/Makefile.am: Include gnulib.mk first so we can append to it.
(AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
(BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
no-longer-necessary initializations.
(lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
* lib/subpipe.c: Include <unistd.h> unconditionally, now that we
use the unistd module.
* src/system.h: Likewise.
* m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
* src/Makefile.am (DEFS): Remove, since configmake does this for us.
(AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
* src/system.h: Include inttypes.h unconditionally, now that we
use the inttypes module. Don't bother to include stdint.h, since
inttypes.h now does that for us.
(LOCALEDIR): Remove, now that we use the configmake module.
* src/getargs.c: Include configmake.h.
* src/main.c: Likewise.
* src/output.c: Likewise.
* tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
not from $abs_top_builddir, since config.h moved.
po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
* bootstrap (gnulib_tool): Stop using --assume-autoconf;
the latest gnulib does this a different way.
(get_translations): Sharuzzaman Ahmat Raslan reported that the ms
translation was patched, so stop omitting it.
* bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
Add fopen-safer.
(gnulib_files): Add m4/warning.m4. Don't worry about files
overwritten by autopoint.
Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
Suppress "id", "ms", "tr" translations for now, since gettext 0.15
rejects them.
Don't use autoreconf; instead, invoke autopoint etc. by hand,
so that we can remove the intl files at a better time.
(intl_files_to_remove): Remove aclocal.m4, since it gets
rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
Remove datarootdir hack; no longer needed.
* configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
(AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
* lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
strdup.h.
* m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
* m4/warning.m4: Remove from CVS, since we now use gnulib's version.
* bootstrap (gnulib_modules): Add stdint.
Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
no longer copies it.
(intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
since stdint needs the former and wcwidth (which is now required
by mbswidth) needs the latter.
Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
work around a compatibility glitch between gettext 0.14.6 and
Autoconf 2.60.
* configure.ac (AC_PREREQ): Require Autoconf 2.60.
Do not check for uintptr_t, since new stdint module does the right
thing.
* lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
Add stdint.h, stdint_.h, wcwidth.h.
* m4/.cvsignore: Remove alloca.m4, onceonly.m4.
Add absolute-header.m4, double-slash-root.m4, longlong.m4,
stdint.m4, wchar_t.m4, wcwidth.m4.
* src/files.c: Include <dirname.h> and <stdio-safer.h> in the
usual order for ../lib/*.h files.
(file_name_split): Use last_component, not base_name, to adjust
to gnulib changes.
* src/parse-gram.h: Include <strverscmp.h> in the usual order
for ../lib/*.h files.
(YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
Define unconditionally, since we now assume the stdint module.
* src/scan-skel.l: Include <dirname.h>.
(BASE_QPUTS): Use last_component, not base_name.
* src/system.h: Include <unlocked-io.h> in the usual order
for ../lib/*.h files. Include <stdint.h> unconditionally,
since we now use the stdint module.
(uintptr_t): Declare if UINTPTR_MAX is not defined, not
HAVE_UINTPTR_T, since we now use the stdint module.
(base_name): Remove decl, since files now include <dirname.h>
to get the decl.
* doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
and "POSIX". Use more-modern syntax for URLs. Mention C++
and ask for Java. Don't hardwire OS version numbers. Add
copyright notice.
* m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
* src/conflicts.c (solved_conflicts_obstack): Now static.
configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
messes up because C++ code is compiled in 32-bit mode but linked
in 64-bit mode.
* lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
compilers that don't understand that abort () does not return.
* src/state.c (transitions_to): Likewise.
* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
that '#include <cstdlib>' works.
* src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
(INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
#undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
for the benefit of some pre-C99 compilers.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space. All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).
* etc/clcommit: Remove. We weren't using it, and it failed
"make maintainer-distcheck".
* Makefile.maint: Merge from coreutils.
(CVS_LIST, CVS_LIST_EXCEPT): New macros.
(syntax-check-rules): Change list of rules as described below.
(sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
(sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):

Use grep -n, to make it easier to find violations.
Use CVS_LIST and CVS_LIST_EXCEPT.

(sc_dd_max_sym_length, .re-list, news-date-check): New rules.
(my-distcheck): Use more-modern GCC flags.
(signatures, %.asc): Remove.
(rel-files, announcement): Remove signatures.
Restore old updating code, even though we don't use it, so
that we're the same as coreutils.

(output_skeleton):
Indent calls to "error" to pacify "make maintainer-distcheck".

"make maintainer-distcheck" complained about.
Create runtime-po files automatically, if possible.
