+	from Autoconf.

+	* data/lalr1.cc (yy::parser::parse): Increase size of

+
+2010-03-20  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	maint: update for changes to gnulib's announce-gen.

+
+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/local.mk (lib_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>
+

+
+	tests: fix missing include caught by g++ 4.4.1.
+	Reported by Tys Lefering.
+	* HACKING (Release checks): Add note about trying a recent GCC.

+	cstdlib for abort.
+	(_AT_DATA_EXPECT2_Y): Likewise.
+
+2010-01-21  Joel E. Denny  <jdenny@clemson.edu>
+
+	* cfg.mk (gnulib_dir): Assume gnulib is a subdirectory.
+
+2010-01-21  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: automate PACKAGE_COPYRIGHT_YEAR update, and update it.
+	* HACKING (Release Procedure): Update notes on copyright years.
+	* Makefile.am (update-package-copyright-year): New target rule.
+	* build-aux/update-package-copyright-year: New file.
+	* cfg.mk (update-copyright): Add update-package-copyright-year

+
+2010-01-19  Joel E. Denny  <jdenny@clemson.edu>

+
+2010-01-15  Joel E. Denny  <jdenny@clemson.edu>
+
+	Thank the developer of the initial push parser implementation.
+	This unfortunate oversight is several years old.
+	* THANKS (Odd Arild Olsen): Add.
+
+2010-01-04  Joel E. Denny  <jdenny@clemson.edu>
+
+	Fix some comments concerning LR(0) versus LALR(1).
+
+	Stop equating LR(0) with nondeterminism and LALR(1) with
+	determinism.  That is, if all states are consistent, then LR(0)
+	tables are deterministic.  On the other hand, LALR(1) tables
+	might be nondeterministic before conflict resolution, and GLR
+	permits LALR(1) tables to remain nondeterministic.
+	* src/LR0.c, src/LR0.h: Here.

+	* src/main.c (main): Here.

+
+2009-12-31  Joel E. Denny  <jdenny@clemson.edu>
+

+
+2009-12-29  Joel E. Denny  <jdenny@clemson.edu>
+
+	portability: `<' and `>' are not always defined on addresses.
+	Specifically, don't sort objects by their memory addresses when
+	they're not allocated in the same array or other object.  Though
+	I haven't found a test case where that fails on my platform, C
+	says the behavior is undefined.
+	* src/AnnotationList.c (AnnotationList__insertInto): Remove
+	FIXME.  Use new id field of InadequacyList nodes rather than
+	their memory addresses when sorting.
+	(AnnotationList__compute_from_inadequacies): Add
+	inadequacy_list_node_count argument to pass to
+	InadequacyList__new_conflict.
+	* src/AnnotationList.h
+	(AnnotationList__compute_from_inadequacies): Update prototype
+	and documentation for new argument.
+	* src/InadequacyList.c (InadequacyList__new_conflict): Add
+	node_count argument and use it to assign a unique ID.
+	* src/InadequacyList.h (InadequacyListNodeCount): New typedef.
+	(InadequacyList): Add id field.
+	(InadequacyList__new_conflict): Update prototype and

+
+2009-12-20  Joel E. Denny  <jdenny@clemson.edu>
+
+	Fix handling of yychar manipulation in user semantic actions.
+	The problem was that yacc.c didn't always update the yychar
+	translation afterwards.  However, other skeletons appear to be
+	fine.  glr.c appears to already translate yychar before every
+	use.  lalr1.cc does not define yychar and does not document its
+	replacement, yyla, for users.  It does provide yyclearin, but
+	that does not manipulate yyla and thus requires no translation
+	update.  In lalr1.java, yychar is out of scope during semantic
+	actions.
+	* NEWS (2.5): Document.
+	* data/yacc.c (YYBACKUP): Don't bother translating yychar into
+	yytoken here.
+	(yyparse, yypush_parse): Instead, translate before every use of
+	yytoken, and add comments explaining this approach.
+	* tests/actions.at (Destroying lookahead assigned by semantic
+	action): New test group checking that translation happens before
+	lookahead destructor calls at parser return.  Previously,
+	incorrect destructors were called.
+	* tests/conflicts.at (parse.error=verbose and consistent
+	errors): New test group checking that translation happens at
+	syntax error detection before the associated verbose error
+	message and the associated lookahead destructor calls.  While
+	the destructor call is fixed by this patch, the verbose error
+	message is currently incorrect due to another bug (see
+	comments in test group), so this is an expected failure for now.

+
+	YYFAIL: warn about uses and remove from lalr1.java.

+	* doc/bison.texinfo (Java Action Features): Remove YYFAIL
+	documentation.
+	(LocalWords): Remove YYFAIL.
+
+2009-12-20  Joel E. Denny  <jdenny@clemson.edu>
+
+	tests: cleanup.

+
+2009-12-18  Joel E. Denny  <jdenny@clemson.edu>
+
