Now, whenever we update bison's copy of gnulib, bootstrap will
update itself the next time it's run.
* bootstrap: Copy from latest gnulib for bootstrap_sync support.
* bootstrap.conf (bootstrap_sync): Set to true.
* gnulib: Update to latest so bootstrap is in sync now.
(cherry picked from commit 10bae98af2)
On master, there is no yychar in lalr1.cc, but there is on
branch-2.5, and the prior cherry-pick of "Fix handling of yychar
manipulation in user semantic actions" wasn't adjusted for that
difference.
* data/lalr1.cc (yy::parser::parse): Translate yychar before
every use of yytoken, and add comments explaining this approach.
* tests/conflicts.at (%error-verbose and consistent errors):
Extend to test yychar manipulation with lalr1.cc.
* NEWS (2.5): Document.
* data/yacc.c (yysyntax_error): In a verbose syntax error
message while in a consistent state with a default action (which
must be an error action given that yysyntax_error is being
invoked), continue to drop the expected token list, but don't
drop the unexpected token unless there actually is no lookahead.
Moreover, handle that internally instead of returning 1 to tell
the caller to do it. With that meaning of 1 gone, renumber
return codes more usefully.
(yyparse, yypush_parse): Update yysyntax_error usage. Most
importantly, set yytoken to YYEMPTY when there's no lookahead.
* data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
unexpected token unless there actually is no lookahead.
* data/lalr1.cc (yy::parser::parse): If there's no lookahead,
set yytoken to yyempty_ before invoking yysyntax_error_.
(yy::parser::yysyntax_error_): Again, don't drop the unexpected
token unless there actually is no lookahead.
* data/lalr1.java (YYParser::parse): If there's no lookahead,
set yytoken to yyempty_ before invoking yysyntax_error.
(YYParser::yysyntax_error): Again, don't drop the unexpected
token unless there actually is no lookahead.
* tests/conflicts.at (%error-verbose and consistent
errors): Extend test group to further reveal how the previous
use of the simple "syntax error" message was too general. Test
yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
failure.
* tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
to...
* tests/local.at: ... here.
(_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
(AT_BISON_OPTION_POPDEFS): Pop it.
(AT_FULL_COMPILE): Extend to handle Java.

These are purely whitespace changes that result in ugly code
but that make the next couple of patches much easier to read.
* data/glr.c (yyreportSyntaxError): Reindent.
* data/lalr1.cc (yy::parser::yysyntax_error_): Reindent.
* data/lalr1.java (YYParser::yysyntax_error): Reindent.

* data/yacc.c (yyparse, yypush_parse): For yysyntax_error
invocation, get rid of the while loop, which is misleading
because there are really at most two iterations.
(cherry picked from commit 34db451c37)
* bootstrap: Copy from gnulib's latest for the fix to
automatically anchor entries it constructs.
* gnulib: Update to latest just so it has the same bootstrap.
* .gitignore, build-aux/.gitignore, doc/.gitignore:
* lib/.gitignore, m4/.gitignore, po/.gitignore:
* runtime-po/.gitignore: Re-anchor all entries.

Jim Meyering reported this in
<http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
* data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
not _STDLIB_H. EXIT_SUCCESS has been defined by the standard
for quite some time.
* src/parse-gram.c, src/parse-gram.h: Regenerate.
* tests/regression.at: Tamper with the renamed witness.

these files, they can resurrect them.
* .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
* m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
Omit leading '/', since bootstrap omits it.
Adjust file names to match current contents better.
* bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
installed just for us.
* bootstrap.conf (excluded_files): Don't exclude codeset.m4,
glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
needed somehow. Don't have time to look into why.
(gnulib_modules): Change malloc to malloc-gnu. Do we really assume
the GNU malloc behavior, where malloc (0) != NULL unless we're
out of storage? If not, we can omit malloc-gnu; but for now I left
it in to be safe.
(vc_ignore): Remove.
* README-hacking: Renamed from HACKING, since gnulib bootstrap now
uses that convention.

* src/complain.c (error_message): Extend to handle incomplete
error messages so warn and warn_at can be used in more cases.
* src/gram.c (grammar_rules_useless_report): Use warn_at so that
-Werror is always obeyed.
* src/reduce.c (reduce_print): Use warn so that the "warnings
being treated as errors" message is printed consistently before
the first warning message. This makes testing easier.
* tests/local.at (AT_BISON_WERROR_MSG): New macro.
