+	maint: add gettext version to release announcements.
+	Suggested by Paul Hilfinger at
+	<http://lists.gnu.org/archive/html/bison-patches/2010-07/msg00019.html>
+	<http://lists.gnu.org/archive/html/bison-patches/2010-08/msg00002.html>.
+	* cfg.mk (bootstrap-tools): Add gettext.
+
+2010-08-04  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	doc: fix -W and %expect documentation some.
+	* NEWS (2.4.3): Mention that there are documentation fixes.
+	* doc/bison.texinfo (Expect Decl): Make it clear that %expect
+	turns conflicts into errors not warnings.
+	(Shift/Reduce): Likewise.
+	(Bison Options): Don't mention -Wsyntax.  It doesn't exist.
+
+2010-08-01  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	-Werror: fix for rules useless in parser after conflicts.
+	* NEWS (2.4.3): Document fix.
+	* src/complain.c (error_message): Extend to handle incomplete
+	error messages so warn and warn_at can be used in more cases.
+	* src/gram.c (grammar_rules_useless_report): Use warn_at so that
+	-Werror is always obeyed.
+	* src/reduce.c (reduce_print): Use warn so that the "warnings
+	being treated as errors" message is printed consistently before
+	the first warning message.  This makes testing easier.
+	* tests/local.at (AT_BISON_WERROR_MSG): New macro.
+	(AT_BISON_CHECK_NO_XML): Extend to check -Werror and
+	--warnings=error when warnings appear in bison's stderr.

+
+2010-05-07  Akim Demaille  <demaille@gostai.com>
+
+	c++: use YYRHSLOC.

+	(b4_percent_define_get): Use it.

+
+2010-05-01  Joel E. Denny  <joeldenny@joeldenny.org>

+	* src/graphviz.c (start_graph): Implement.
+
+2010-04-30  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	Document that undefined %prec identifier warnings will remain.
+	* NEWS (2.4.3): Here.
+	(2.4.2): Here.
+
+2010-04-30  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	Revert 2009-12-30 change for undefined %prec token complaints.
+	That is, keep them as warnings because that should be sufficient
+	to satisfy POSIX without creating backward compatibility issues.
+	Suggested by Richard Stallman at

+	* bootstrap.conf (bootstrap_epilogue): New function to make sure

+
+2010-04-25  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	i18n: fix untranslatable string.
+	Reported by Goran Uddeborg at

+
+2010-04-13  Akim Demaille  <demaille@gostai.com>
+

+	* tests/local.at (AT_LOC_PUSHDEF, AT_LOC_POPDEF): New.
+	(_AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): Use them to
+	define the appropriate AT_LOC accessors.
+	* tests/calc.at: Use AT_LOC accessors.
+
+2010-04-13  Akim Demaille  <demaille@gostai.com>
+
+	test location_type.
+	* tests/local.at (_AT_BISON_OPTION_PUSHDEFS):
+	Define AT_LOCATION_TYPE_IF.
+	(_AT_BISON_OPTION_POPDEFS): Undefine AT_LOCATION_TYPE_IF.
+	* tests/calc.at (_AT_DATA_CALC_Y): When %define location_type is
+	used, provide a user location type and use it.
+	(Simple LALR1 C++ Calculator): Add a test case for location_type.
+
+2010-04-13  Akim Demaille  <demaille@gostai.com>
+
+	tests: check fclose's return value.
+	* tests/calc.at (_AT_DATA_CALC_Y): Check fclose's return status.
+
+2010-04-13  Akim Demaille  <demaille@gostai.com>
+
+	tests: don't depend on the actual location type.
+	* tests/calc.at: Use yy::parser::location_type rather than
+	yy::location, since the former is always right, and might point to
+	another type than the latter.
+
+2010-04-13  Akim Demaille  <demaille@gostai.com>
+
+	formatting changes.
+	* tests/calc.at: Formatting changes.

+
+	lalr1.cc: remove useless forward declaration.
+	* data/lalr1.cc: Include location.hh before stack.hh.
+	Remove the useless forward declarations of position and location.

+	* THANKS (Dagobert Michelsen): Add.
+	* configure.ac (AC_PREREQ): Set to 2.64 so we get the latest
+	Autoconf macro for handling the restrict keyword.
+	* gnulib: Update to latest, which no longer overrides that macro
+	from Autoconf.
+
+2010-04-03  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	portability: fix pointer arithmetic to conform to C standard.
+	Reported by Tys Lefering at
+	<http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00035.html>.
+	This fix is already implemented in glr.c and does not apply to
+	lalr1.java.
+	* data/lalr1.cc (yy::parser::parse): Increase size of
+	yyerror_range and adjust subscripting so you don't have to
+	subtract one from the beginning of the array.
+	* data/yacc.c (b4_declare_parser_state_variables,
+	yyparse, yypush_parse): Likewise.
+
+2010-04-05  Akim Demaille  <demaille@gostai.com>

+
+2010-03-25  Akim Demaille  <demaille@gostai.com>

+
+	portability: fix for BSD make.
+	Reported by Johan van Selst at

+
+	portability: fix spawning on at least FreeBSD 8 and FreeBSD 9.
+	Reported by Johan van Selst at
+	<http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00014.html>.
+	* NEWS (2.4.3): New.
+	* THANKS (Johan van Selst): Add.
+	* gnulib: Update to latest.
+
+2010-03-20  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	maint: update for changes to gnulib's announce-gen.
+	* HACKING (Announce): RELEASE_TYPE=major must now be written
+	RELEASE_TYPE=stable.
+
+2010-03-20  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Version 2.4.2.
+	* NEWS (2.4.2): Set version and date.  For the recent test suite
+	portability fixes, don't be so optimistic about their success
+	given the lack of feedback on the affected platforms.
+
+2010-02-22  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	tests: fix maintainer-xml-check for recent changes.
+	* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use
+	AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an
+	output file whose name conflicts with a previous output file
+	is now never generated.
+
+2010-02-22  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	portability: fix several issues with M4 subprocess.
+
+	M4's output pipe was not being drained upon fatal errors during
+	scan_skel.  As a result, broken-pipe messages from M4 were seen
+	on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
+	failure in the test suite.  The problem was that, on platforms
+	where the default disposition for SIGPIPE is ignore instead of
+	terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
+	then reported it.  However, there's some sort of race condition,
+	because the new test group occasionally succeeded.
+	Reported by Albert Chin at
+	<http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
+
+	There were also problems with the test suite livelocking on
+	Tru64 5.1b.  Reported by Didier Godefroy at
+	<http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
+	Switching to create_pipe_bidi suggested by Akim Demaille.
+
+	To attempt to solve both of these problems, switch to gnulib's
+	create_pipe_bidi and register M4 process as a slave.  Along the
+	way, clean up file name conflict handling, which was affected by
+	the broken-pipe problem before the switch.
+	* NEWS (2.4.2): Document.
+	* THANKS (Didier Godefroy): Add.
+	* bootstrap.conf (gnulib_modules): Add pipe.
+	* gnulib: Update to latest to make sure we have all the latest
+	fixes.
+	* lib/Makefile.am (libbison_a_SOURCES): Remove subpipe.h and
+	subpipe.c.
+	* po/POTFILES.in (lib/subpipe.c): Remove.
+	* src/files.c (compute_output_file_names): Update invocations
+	of output_file_name_check.
+	(output_file_name_check): In the case that the grammar file
+	would be overwritten, use complain instead of fatal, but replace
+	the output file name with /dev/null.  Use the /dev/null solution
+	for the case of two conflicting output files as well because it
+	seems safer in case Bison one day tries to open both files at
+	the same time.
+	* src/files.h (output_file_name_check): Update prototype.
+	* src/output.c (output_skeleton): Use create_pipe_bidi and
+	wait_subprocess.  Assert that scan_skel completely drains the
+	pipe.
+	* src/scan-skel.l (at_directive_perform): Update
+	output_file_name_check invocation.
+	* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the
+	grammar file actually isn't overwritten.
+	(Conflicting output files: -o foo.y): Update expected output.
+	* tests/skeletons.at (Fatal errors but M4 continues producing
+	output): New test group.
+
+2010-02-04  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Update POTFILES.
+	* HACKING (Release Procedure): Add reminder about keeping
+	POTFILES files up-to-date.
+	* po/POTFILES.in (src/muscle-tab.c, src/scan-skel.l): Add.
+
+2010-02-01  Joel E. Denny  <jdenny@clemson.edu>
+
+	Code cleanup.
+	* tests/atlocal.in (abs_top_srcdir): Remove shell variable,
+	which is already defined in atconfig.
+
 2010-01-21  Joel E. Denny  <jdenny@clemson.edu>
 
 	* cfg.mk (gnulib_dir): Assume gnulib is a subdirectory.
