+	* src/scan-code.l: Fix prototypes and adjust names.
+	* src/named-ref.c: Remove redundant "if".
+
+2009-07-29  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Fix a --enable-gcc-warnings problem.
+	* src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
+	variable.
+
+2009-07-24  Alex Rozenman  <rozenman@gmail.com>
+
+	Fix some memory leaks.
+	* src/named-ref.c: Add a pointer check (named_ref_free).
+	* src/scan-code.l: New function (variant_table_free). Called in
+	code_scanner_free.
+	* src/symlist.c: Call to named_ref_free (symbol_list_free).
+
+2009-07-24  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Warn about character literals not of length one.
+	* NEWS (2.5): Document.
+	* src/scan-gram.l (INITIAL): Remove comment that we don't check
+	the length.
+	(SC_ESCAPED_CHARACTER): Warn if length is wrong.
+	* tests/input.at (Bad character literals): New test group.
+
+2009-07-24  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* src/lalr.c (state_lookahead_tokens_count): Correct comment.
+
+2009-07-22  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Some M4 cleanup in the testsuite.
+	Suggested by Eric Blake at
+	<http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
+	* tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
+	complicate the code by distinguishing between a missing value
+	and an empty string value for an optional argument.  This fix is
+	allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
+	* tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
+	(AT_TEST_TABLES_AND_PARSE): ... this now that the special
+	arguments are not needed because of the following changes.
+	Fix stale comments.
+	Bison developers should use GNU M4 and should not use
+	POSIXLY_CORRECT when building the test suite, so do not
+	complicate the code by avoiding $10 and above.
+	Do not quote an empty string value for an optional argument, and
+	do not distinguish between a missing value and an empty string
+	value.
+
+2009-07-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* m4/m4.m4: Make it a sym link to submodules/autoconf/m4/m4.m4.
+
+2009-07-15  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Revert unnecessary column realignment in --help output.
+	Reported by Akim Demaille at
+	<http://lists.gnu.org/archive/html/bison-patches/2009-06/msg00010.html>.
+	* src/getargs.c (usage): Here.
+
+2009-07-04  Alex Rozenman  <rozenman@gmail.com>
+
+	Alphabetical order in src/Makefile.am.
+	* src/Makefile.am: Adjust.
+
+2009-07-04  Alex Rozenman  <rozenman@gmail.com>
+
+	Style changes and factoring.
+	* src/named-ref.h: Add comments.
+	* src/parse-gram.y: Readability and style changes.
+	* src/reader.c: Factoring: assign_named_ref function.
+	* src/scan-code.l: Factoring and style changes. Rename
+	parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
+	Use "unsigned" type for variant index. Improve readablity.
+	* src/scan-gram.l: Change error messages and add comments.
+	* src/symlist.h: symbol_list_null: New function decl.
+	* src/symlist.c: symbol_list_null: Implement here.
+	* tests/named-refs.at: Adjust for new error messages.
