84526bf3d1 maint: don't use mbsr?chr. 
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 (gnulib_modules): Request it.
* src/output.h, src/output.c (compute_pkgdatadir): Rename as...

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>.

ef51bfa744 c++: use nullptr for C++11. 
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.

4c787a31df use a more consistent quoting style. 
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.

e187b40d31 do not ignore errors like ENOSPC,EIO when writing to stdout 
Standard output was never explicitly closed, so we could not
detect failure.  Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
rather than standard output.
* bootstrap.conf (gnulib_modules): Add closeout.
* src/main.c: Include "closeout.h".
Use atexit to ensure we close stdout.
* .gitignore: Ignore new files pulled in via gnulib-tool.
