+
+2010-05-01  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	In DOT output, convert from "/*" comments to "//" comments.
+	This handles the possibility that a "*/" might appear in

+	* 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

+
+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.

+
+2010-04-10  Joel E. Denny  <joeldenny@joeldenny.org>
+
+	tests: fix for newer Sun Studio C++.
+	Reported by Dagobert Michelsen at
+	<http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00023.html>.
+	* 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.
+

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

+
+	portability: fix for BSD make.

+	Reported by Johan van Selst at

+	* NEWS (2.4.3): New.

+	* 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.
+
+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
+	as a dependency.
+
+2010-01-19  Joel E. Denny  <jdenny@clemson.edu>
+
+	* bootstrap: Import improvements from latest gnulib.
+
+2010-01-19  Joel E. Denny  <jdenny@clemson.edu>
+
+	build: require Automake 1.11.1 to avoid a security flaw.
+	* HACKING (Release Procedure): Don't document Automake security
+	flaw here.
+	* configure.ac (AM_INIT_AUTOMAKE): Require 1.11.1, and explain

+
+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/lalr.c, src/lalr.h: Here.
+	* src/main.c (main): Here.
+	* src/state.c, src/state.h: Here.
+
+	* src/ielr.h (ielr): In preconditions, expect LR(0) not LALR(1)
+	parser tables.
+

+
+	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 (%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.

+	yysyntax_error: avoid duplicate lookahead collection.
+	Except when memory reallocation is required, this change
+	eliminates the need to invoke yysyntax_error twice and thus to
+	repeat the collection of lookaheads.  It also prepares for
