* cfg.mk (exclude_file_name_regexp--sc_space_tab): Exempt
tests/input.at and tests/c++.at, since they appear to use
SP-TAB sequences deliberately.
* OChangeLog: Remove space-before-TAB.
* bootstrap.conf (gnulib_modules): Add gpl-3.0.
* doc/gpl-3.0.texi: Remove from version control, now that
we get it via gnulib.
* doc/.gitignore: Ignore it.
* lib/lbitset.c (lbitset_elt_find): Remove unnecessary test of "elt",
at a point where we know it is non-NULL, due to prior dereference.
Copyright (C) 1987-1988, 1991-2012 Free Software Foundation,
* lib/bitset_stats.c (bitset_stats_list): Remove declaration
and set of unused local, "type".
* lib/ebitset.c (ebitset_init): Likewise, for "size".
* lib/lbitset.c (lbitset_not): Likewise, for "elt".
This should help to avoid some portability problems. For example,
it would have revealed the empty unions fixed by the last patch
* configure.ac (WARN_CFLAGS_TESTS, WARN_CXXFLAGS_TEST): Implement.
* tests/synclines.at (AT_TEST_SYNCLINE): Avoid -pedantic warning
about an empty translation unit.
(cherry picked from commit 5422d56a71)
Empty unions are not accepted by the ISO C99 grammar or by at
least some versions of Sun Studio. Reported by Wolfgang S. Kechel

* NEWS (2.5.1): Document fix.
* THANKS (Wolfgang S. Kechel): Add.
* tests/existing.at (GNU Cim Grammar)
(GNU pic (Groff 1.18.1) Grammar.): Remove empty %union.
(cherry picked from commit 7451638148)
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
The typo shows up in the `configure --help' output. Reported by
W.C.A. Wijngaards and Paul Eggert at
<http://lists.gnu.org/archive/html/bug-bison/2011-07/msg00000.html>.
* README-hacking (Release Procedure): Remind about updating
maintainer tools before a release.
* THANKS (W.C.A. Wijngaards): Add.
* configure.ac (AC_PREREQ): Set to 2.68, which fixes the YACC
typo.
(cherry picked from commit 845346b3bb)
* doc/bison.texinfo (Locations Overview): Rename node to...
(Locations): ... this, which is its section name. Update menus to
match that and not to use the title `Tracking Locations', which is
a different section.
(cherry picked from commit 8348436580)
* doc/bison.texinfo (Locations): Rename node to...
(Tracking Locations): ... this, which is its section name, and
update all cross references. The trouble is that there is another
node about locations. Its section name is `Locations', which was
easily confused with the node name of this node. Moreover, its
node name is `Locations Overview', which was mistakenly used to
label some cross references to this node.
(cherry picked from commit 7404cdf3a1)
Conflicts:
doc/bison.texinfo
* doc/bison.texinfo (Named References): Rename section to match
the node name, and update all cross references. Don't use the
acronyms RHS and LHS given that we don't expand them anywhere in
the manual. Try to use @samp and @code properly. Mention that
named references are experimental as we've already stated in NEWS.
(Destructor Decl): Expand the only remaining use of RHS or LHS.

* NEWS (2.5.1): Document.
* doc/bison.texinfo (Named References): Because it discusses
locations in addition to semantic values, move this subsection out
of the section `Defining Language Semantics', where locations have
not yet been introduced, to be a new section after the following
section, `Tracking Locations'.
(cherry picked from commit 908c8647de)
It creates unnecessary differences between the sources that Bison
maintainers build and test (given that maintainers normally
configure with --enable-gcc-warnings) and the sources that Bison
users build. Instead, use PACIFY_CC, which doesn't. This change
fixes compiler warnings reported by Tys Lefering at
<http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
* configure.ac: Don't AC_DEFINE lint regardless of the configure
options. This change affects imported gnulib sources, where
IF_LINT still appears and depends on lint.
* src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
PACIFY_CC.
* src/system.h (IF_LINT): Remove cpp macro.
(PACIFY_CC): New cpp macro.

Since Bison 2.3b, which restored the ability of precedence
directives to assign user token numbers, doing so for user token
number 0 has produced an assertion failure.
* NEWS (2.5): Document fix.
* src/symtab.c (symbol_user_token_number_set): In the case of the
end token, don't decrement ntokens if it was never incremented.
* tests/regression.at (Token number in precedence declaration):
Extend.
(cherry picked from commit 9d6af15318)
* bootstrap.conf (gnulib_modules): Add all modules suggested by
-DGNULIB_POSIXCHECK.
* src/files.c (file_name_split)
* src/getargs.c (getargs)
* src/location.c (boundary_set_from_string)
* src/output.c (output_skeleton)
* src/parse-gram.y (prologue_declaration)
* src/scan-gram.l (handle_syncline)
* src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of
strchr and strrchr. In the cases of command-line options, file
names, and thus locations, functionality may be improved. In the
case of symbol names, there should be no functional difference as
all characters are ASCII, so the intended benefit is just warning
suppression.
(cherry picked from commit d143e9c33f)
Conflicts:
src/output.c

* NEWS (2.5): For multi-character tokens in example grammar rules,
use "token" not 'token'. In English, use a consistent quotation
style; we might as well follow the precedent seen in info pages:
`quote' not "quote".

This prevents gcc 4.6.0's -Wunused-but-set-variable from warning
about yyresolveLocations's local yyrhsloc. When locations are
enabled, there's no such warning because YYLLOC_DEFAULT then uses
yyrhsloc. Reported by Jim Meyering at
<http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>.
* data/glr.c (yyresolveLocations): Omit definition when locations
are disabled.
(yyresolveValue): Omit yyresolveLocations invocation when
locations are disabled.
(cherry picked from commit 55dd356336)
* README-hacking (Updating a submodule): Give advice on how to
determine the versions of gnulib and autoconf to which we should
update.
(Release Procedure): Note that submodules should be updated.
* bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as
suggested in updated gnulib NEWS.
* gnulib: Choose a stable snapshot according to advice in Bison's
README-hacking.
* po/POTFILES.in (lib/pipe.c): Rename to...
(lib/spawn-pipe.c): ... this.
* src/output.c: Update to include spawn-pipe.h.
* submodules/autoconf: Update to latest for improvement in m4.m4
that excludes M4 with buggy strstr. The only other changes to
files that we use are copyright updates.
