+
+	* Makefile.maint: Merge with coreutils Makefile.maint.
+	(CVS_LIST): Use build-aux version if available.
+	(VERSION_REGEXP): New macro.
+	(syntax-check-rules): Add sc_no_if_have_config_h,
+	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.
+	* src/reader.c (packgram): Prepend a new sentinel before ritem.
+	* src/lalr.c (build_relations): Rely on new sentinel.
+	* src/gram.c (gram_free): Adjust to new sentinel.

+2006-01-12  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* 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.

+
+	* data/glr.c (yyaddDeferredAction): Flesh out the comment.
+
+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.
