+
+ Fix precedence for end token.
+ 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.
+
+2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Pacify -DGNULIB_POSIXCHECK.
+ * 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.

+
+ doc: clean up quotation style in NEWS.
+ * 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".

+ tests: pacify gcc 4.6.0's -Wunused-but-set-variable.

+
+ glr.c: omit yyresolveLocations when locations are disabled.
+ 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.

+ locations are disabled.

+ * 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

+ that excludes M4 with buggy strstr. The only other changes to
+ files that we use are copyright updates.

+
+2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>

+ (%define Summary): Condense the entries for lr.default-reductions,

+ * doc/bison.texinfo (Decl Summary): Extract most of the %define
