+ (CVS_LIST): Use build-aux version if available.
+ (VERSION_REGEXP): New macro.

+ sc_prohibit_assert_without_use, sc_require_config_h,
+ sc_useless_cpp_parens.
+ (sc_obsolete_symbols): Check for O_NDELAY.
+ (sc_dd_max_sym_length): Track coreutils.
+ (sc_unmarked_diagnostics): Look in all files, not just *.c.
+ (sc_useless_cpp_parens): New rule.
+ (news-date-check): Look for version or today's date.
+ (changelog-check): Don't require version number near head.
+ (copyright-check): Use current year instead of hardwiring 2005.
+ (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
+ (announcement): Add --gpg-key-ID.
+
+ * djgpp/config.sed: Add copyright notice, and replace "filesystem"
+ with "file system".
+
+ Avoid undefined behavior that accessed just before the start of an
+ array. Problem reported by twlevo.

+
+ * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
+ yylookaheadNeeds. All uses updated.
+ (yysplitStack): Rename local yynewLookaheadStatuses to
+ yynewLookaheadNeeds.
+ * data/glr-regression.at (Incorrect lookahead during nondeterministic
+ GLR): In comments, change `lookahead status' to `lookahead need'.

+
+ * data/glr.c (yysplitStack): A little stylistic rewrite.

+2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo: Fix some typos.
+ (GLR Semantic Actions): New subsection discussing special
+ considerations because GLR semantic actions might be deferred.
+ (Actions): Mention look-ahead usage of yylval.
+ (Actions and Locations): Mention look-ahead usage of yylloc.
+ (Special Features for Use in Actions): Add YYEOF entry and mention it
+ in the yychar entry.
+ In the yychar entry, remove mention of the local yychar case (pure
+ parser) since this is irrelevant information when writing semantic
+ actions and since it's already discussed in `Bison Symbols' where
+ yychar is otherwise described as an external variable.
+ In the yychar entry, don't call it the `current' look-ahead since it
+ isn't when semantic actions are deferred.
+ In the yychar and yyclearin entries, add note about deferred semantic
+ actions.
+ Add yylloc and yylval entries discussing look-ahead usage.
+ (Look-Ahead Tokens): When discussing yychar, don't call it the
+ `current' look-ahead, and do mention yylval and yylloc.
+ (Error Recovery): Cross-reference `Action Features' when mentioning
+ yyclearin.
+ (Bison Symbols): In the yychar entry, don't call it the `current'
+ look-ahead.
+ In the yylloc and yylval entries, mention look-ahead usage.

!yyvaluep as signal that no semantic value is available to print.
* data/glr.c (yydestroyGLRState): If state is not resolved, don't try
to print a semantic value.
