+
+	Pacify "gcc -Wunused" for the input function from Flex.
+	Reported by Alex Rozenman.  This warning shows up with gcc-4.3.0
+	and later.
+	* src/scan-code.l: Add "%option noinput", which I cannot find in
+	the Flex manual, but which Flex has supported since at least as
+	far back as 2.5.4.  However, if any of our developers still use
+	Flex 2.5.4, they'll need to stop configuring with
+	--enable-gcc-warnings because "%option noinput" didn't work
+	correctly until Flex 2.5.6.
+	* src/scan-gram.l: Likewise.
+	* src/scan-skel.l: Likewise.

+	* src/scan-code.l: Fix prototypes and adjust names.
+	* src/named-ref.c: Remove redundant "if".

+
+	Fix a --enable-gcc-warnings problem.
+	* src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
+	variable.
+
+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  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>
+
+	* src/lalr.c (state_lookahead_tokens_count): Correct comment.

+
+	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+	Do not quote an empty string value for an optional argument, and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.
+
+2009-07-15  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.
+

 	Alphabetical order in src/local.mk.
 	* src/local.mk: Adjust.
