Basically, revert ba60c39547a445dee3e07920931b4d7a81843868's move to
mbs* functions, which was prompted by -DGNULIB_POSIXCHECK. See
<http://lists.gnu.org/archive/html/bison-patches/2012-05/msg00052.html>
and following.
* bootstrap.conf: No longer ask for them.
* src/files.c, src/getargs.c, src/location.c,
* src/parse-gram.c, src/parse-gram.y, src/scan-gram.l,
* src/symtab.c: s/mbs(r?chr)/str$1/g.
* bootstrap.conf (gnulib_modules): Request it.
* src/output.h, src/output.c (compute_pkgdatadir): Rename as...
(pkgdatadir): this.
Adjust dependencies.
* src/output.c (output_skeleton): Reduce the scope of "in".
Use xconcatenated_filename to simplify the construction of the
qualified paths to m4sugar.m4, bison.m4, and the selected skeleton.
There are a few minor differences: the new code uses strchr instead of
mbschr (but this was not really justified), and the new code does not
garantee a single slash even if $BISON_PKGDATADIR ends with several
(which was considered more accurate). See the discussion at
<http://lists.gnu.org/archive/html/bison-patches/2012-05/msg00052.html>.
Using http://github.com/lyda/misspell-check, massage its
output into sed commands to perform the suggested changes.
Initially, I filtered out the THRU->Through changes, because
that failed to retain capitalization in the grammar token.
Instead, do this manually, beforehand:
sed -i s/THRU/THROUGH/ tests/existing.at
git ls-files|misspellings -f -|perl -nl \
-e '/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/ or next;' \
-e '($file,$n,$l,$r)=($1,$2,$3,$4); $q="'\''"; $r=~s/$q/$q\\$q$q/g;'\
-e 'print "sed -i $q${n}s!$l!$r!$q $file"'|bash
Some versions of Flex, possibly modified by the distribution package
maintainers, have incompatible signatures. Since newer versions of
Flex prototype their functions, avoid the conflicts in that case.

* src/flex-scanner.h (FLEX_VERSION_GT): New.
Use it to issue prototypes for flex-generated functions only for
versions up to 2.5.31, in accordance with the comment.
See commit dc9701e848.
Use it to define yylex_destroy when needed.
* src/parse-gram.y (add_param): Use xmemdup0 in place of
xmalloc+memcpy, and strspn in place of an open-coded loop.
Co-authored-by: Akim Demaille <akim@lrde.epita.fr>
* src/output.c (output_skeleton): Use memcpy, not strncpy,
since the source is known to fit in the destination buffer.
* src/parse-gram.y (%skeleton): Likewise.
* origin/maint:
bump to 2012 in skeletons.
build: remove ancient Autoconf tests.
doc: c++: complete the location documentation.
c++: locations: provide convenience constructors.
c++: locations: remove useless "inline".

c++: use nullptr for C++11.
build: simplify and improve the compiler warnings for tests.
gnulib: update.
maint: formatting changes.
NEWS: update.
Java: Fix syntax error handling without error token.
tests: beware of -pedantic on large #line numbers.

C++11 introduces "nullptr" which plays the role of C's NULL, in
replacement of "0". Fix the C++ skeletons to avoid warnings about
uses of "0" in place of "nullptr", and improve C skeletons to also use
this "nullptr" when compiled with a C++11 compiler.
* configure.ac: More C++ warnings.
* NEWS (2.5.1): Document this.
* data/c++.m4, data/c.m4 (b4_null_define): New.
(b4_null): Use YY_NULL instead of 0.
* data/glr.c, data/lalr1.cc, data/location.cc, data/yacc.c:
Call b4_null_define/b4_null where appropriate.
Use YY_NULL instead of NULL.
* data/location.cc (initialize): Accept a default argument,
YY_NULL.
* tests/actions.at, tests/calc.at: Adjust.
* data/glr.c, lib/libiberty.h, src/system.h (__attribute__):
Do not disable it when __STRICT_ANSI__ is defined, as, for
instance, it disables the __attribute__((unused)) which
protects us from some compiler warnings.
This was already done elsewhere in Bison, in 2001, see
4a0d893695.
* tests/regression.at: Adjust output.
Before this change, bison would accept either .tab and _tab equivalently,
whatever the current platform. Besides, it was not obeying everywhere
to the possible definition of TAB_EXT to something else than .tab.
For consistency, handle only TAB_EXT (".tab" on non DJGPP platforms).
Support for "_tab" is neither documented, nor tested.
* src/system.h (STRNCMP_LIT): New.
From Jim Meyering.
(STRPREFIX_LIT): New.

* src/uniqstr.c:
Use them.
* src/scan-gram.l: Do not use streq.h, use system.h's STREQ.
* cfg.mk: The documentation is an exception.
Exit status 63 is documented for version-mismatch.
* bootstrap.conf (gnulib_modules): Remove sysexits.
* src/system.h (EX_MISMATCH): Define.
* src/parse-gram.y (version_check): Use it instead of EX_CONFIG.
Missing includes.
* tests/calc.at, tests/named-refs.at: Include assert.h.

Move other options in here.
(BISON): New.
(YACC): Use it.
(bison_SOURCES): Now that automake can see `-d' in AM_YFLAGS,
we can rely on it to compile and ship the parser header
files.
Based on commit 737406a32c and
commit 3d6ca33908.
* src/local.mk: Put yacc related variables together.
(AUTOMAKE_OPTIONS): Move to...
* Makefile.am: here.
Remove an old Emacs mode request which disables Automake support.
* src/local.mk (YACC, AM_YFLAGS): Move to...
* Makefile.am: here, as they will be used by other local.mks.
The directory was still using a local Makefile.am because it provides
"scoped" Make variables: these examples are not meant to use the same
CPPFLAGS etc. If we were to use the same -I set, we'd pick up
gnulib's stdio.h for instance, which we do not want for these simple
examples.
Yet, as a result, the dependencies are less accurate, there is code
duplication, etc. This is especially perceptible when trying to
extract more examples from the documentation, as will be done in
forthcoming changes.
In order to make the tuning of CPPFLAGS easier, discard the predefined
-I from Automake.
* examples/calc++/Makefile.am: Rename as...
* examples/calc++/local.mk: this.
Adjust the paths which are now rooted in top_srcdir/top_builddir.
Handle BISON_CXX_WORKS here, instead of the too crude previous
approach that completely discarded the whole directory.
($(BISON)): Remove now useless bouncing recipe.
(calc___CPPFLAGS): New.
Stay away from -Ilib.
* Makefile.am, configure.ac, examples/local.mk,
* examples/calc++/test: Adjust.
* configure.ac: Pass nostdinc to Automake.
* src/local.mk, lib/local.mk (AM_CPPFLAGS): Move to...
* Makefile.am: here.
* src/local.mk, examples/calc++/Makefile.am (BISON, BISON_IN): Factor
to...
* Makefile.am: here.
* tests/local.mk: Use it.
See <http://lists.gnu.org/archive/html/bug-bison/2012-01/msg00120.html>.
Use quotearg as often as possible instead of leaving the choice of
the quotes to the translators. Use shorter messages. Factor similar
messages to a single format, to make localization easier.
* src/files.c, src/getargs.c, src/muscle-tab.c, src/reader.c
* src/scan-code.l, src/scan-gram.l, src/symtab.c:
Use quote() or quotearg_colon() on printf arguments instead of
quotes in the format string.
* data/bison.m4: Keep sync with the changes in muscle-tab.c.
* tests/skeletons.at, tests/input.at, tests/regression.at: Adjust
expected messages.
