+	doc: %initial-action to initialize yylloc.
+	Reported by Bill Allombert.
+	* doc/bison.texinfo: Set fill-column to 76.
+	(Location Type): Document the use of %initial-action to initialize
+	yylloc.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+	lalr1.cc: use state_type.
+	* data/lalr1.cc (yysyntax_error_): Use state_type.
+	Move argument names into yy*.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+	lalr1.cc: get rid of yyparse's yystate.
+	yystate and yystack_[0].state are equal, keep only the latter.
+	The former was also used as a temporary variable to compute the
+	post-reduction state.  Move this computation into an auxiliary
+	function.
+
+	* data/glr.c (yyLRgotoState): Fuse variable definition and first
+	assignment.
+	* data/lalr1.cc (yy_lr_goto_state_): New.
+	(yyparse): Use it.
+	Replace remaining uses of yystate by yystate_[0].state.
+	Remove the former.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+	lalr1.cc: destroy $$ when YYERROR is called.
+	* data/lalr1.cc (yyreduce): Compute the resulting state before
+	running the user action so that yylhs is a valid symbol.
+	(yyerrorlab): Since yylhs is complete (it knows its type), we can
+	simply call yy_destroy_ to destroy $$ on YYERROR invocations.
+	* tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.

+
+	maint: update for gnulib's recent update-copyright changes
+	* gnulib: Update.
+	* .x-update-copyright (COPYING): Add as it's no longer implied
+	when .x-update-copyright is present.
+	* cfg.mk (update-copyright-local): Remove, now ignored.
+	(update-copyright): Declare update-b4-copyright as a dependency.

+	build: require gettext 0.17.
+
+	Suggested by Bruno Haible.
+	http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
+	* configure.ac: require gettext 0.17 to ensure compatibility with
+	gnulib.
+
+2009-08-17  Akim Demaille  <demaille@gostai.com>
+
+	build: lower gettext requirements.
+
+	Bison was uselessly requiring the formatstring macros from
+	gettext, which resulted in mo files not being installed on systems
+	that perfectly supported Bison mo files.  Lower the requirement.
+	http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
+
+        * configure.ac: Require need-ngettext instead of
+        need-formatstring-macros.
+        Reported by Martin Jabocs.
+        Suggested by Bruno Haible.
+        * INSTALL: Restructure.
+        (Internationalization): New.
+
+2009-08-14  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: fix use of copyright year intervals.
+	* gnulib: Update.
+	* bootstrap.conf (gnulib_modules): Update getopt to getopt-gnu
+	as now recommended in gnulib/NEWS.
+	* build-aux/update-b4-copyright: Fix.
+	* cfg.mk (update-copyright-env): Configure update-copyright.
+
+2009-08-13  Joel E. Denny  <jdenny@clemson.edu>
+
+	Make it easier to write deterministic tests.
+	Continues Akim's work from his 2009-06-10 commits.
+	* src/reader.c (check_and_convert_grammar): Don't add any
+	symbols after the first symbols_do invocation.
+	* src/symtab.c (symbols_sorted): New static global.
+	(user_token_number_redeclaration): Update comments.
+	(symbol_from_uniqstr): If a new symbol is being created, assert
+	that symbols_sorted hasn't been allocated yet.
+	(symbols_free): Free symbols_sorted.
+	(symbols_cmp, symbols_cmp_qsort): New functions.
+	(symbols_do): Sort symbol_table into symbols_sorted on first
+	invocation.
+	* tests/input.at (Numbered tokens): Recombine tests now that the
+	output should be deterministic across multiple numbers.
+
+2009-08-12  Akim Demaille  <demaille@gostai.com>
+
+	tests: GCC 4.5 compliance.
+	* tests/synclines.at (AT_SYNCLINES_COMPILE): Adjust to GCC 4.5's
+	messages about #error.
+
+2009-08-12  Akim Demaille  <demaille@gostai.com>
+
+	build: fix the generation of the documentation.
+	Some of our targets use "bison --help", but they can't depend on
+	"bison" itself (to avoid additional requirements on the user), so
+	they used to call "make src/bison" in the commands.  Then
+	concurrent builds may fail: one make might be aiming one of its
+	jobs at compiling src/bison, and another job at generating the man
+	page.  If the latter is faster than the former, then we have two
+	makes that concurrently try to compile src/bison.
+
+	This might also be a more convincing explanation for the failure
+	described in the patch "build: fix paths".
+
+	* Makefile.am (SUFFIXES): Initialize.
+	* build-aux/move-if-change: New, symlink to gnulib's.
+	* build-aux/local.mk: Ship it.
+	* doc/common.x: Remove, merged into...
+	* doc/bison.x: here.
+	* doc/local.mk (doc/bison.help): New.
+	($(CROSS_OPTIONS_TEXI)): Depend on it.
+	Use src/bison.
+	(.x.1): Replace with...
+	(doc/bison.1): this explicit, simpler, target.
+	(common_dep): Remove, inlined where appropriate.
+	(SUFFIXES, PREPATH): Remove, unused.
+
+2009-08-12  Akim Demaille  <demaille@gostai.com>
+
+	gnulib: improve prefixing.
+	* configure.ac (gl_PREFIXED_LIBOBJS): Don't rename it, rather,
+	change the value of...
+	(gl_LIBOBJS): this.
+	Adjust more variables.
+	* etc/prefix-gnulib-mk (prefix_assignment): Don't rename
+	gl_LIBOBJS.
+	(prefix): Also transform rules whose targets have slashes.
+	Use $prefix liberally.
+	Map @MKDIR_P@ to $(MKDIR_P).
+	Prefix directories that are mkdir'd.
+
+2009-08-12  Akim Demaille  <demaille@gostai.com>
+
+	build: fix paths.
+	When using $(top_builddir) inconsistently, Make (including GNU
+	Make) is sometimes confused.  As a result it may want to build
+	lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
+	file, different names) concurrently, which, amusingly enough,
+	might end with:
+
+	  ranlib lib/libbison.a
+	  ranlib lib/libbison.a
+	  make[2]: *** [lib/libbison.a] Segmentation fault
+
+	on OS X.
+
+	* doc/local.mk, src/local.mk: Do not use $(top_builddir) when not
+	needed.
+
+2009-08-12  Akim Demaille  <demaille@gostai.com>
+
+	distcheck: fix.
+
+        * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.
+
+2009-08-10  Joel E. Denny  <jdenny@clemson.edu>
+
+	* tests/local.mk (TESTSUITE_AT): Add named-refs.at.
+
+2009-08-10  Joel E. Denny  <jdenny@clemson.edu>
+
+	Miscellaneous code readability improvements.
+
+	* src/reader.c (reader): Move %define front-end variable
+	defaults and checking into...
+	(prepare_percent_define_front_end_variables): ... this new
+	function.
+
+	* src/scan-gram.l (INITIAL): For consistency with string
+	literals, don't store open quote on character literal.  It's
+	discarded before returning anyway.
+	(SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
+	Make length test more readable, and make the character stored
+	for an empty literal more obvious while consistent with the
+	previous behavior.
+
+	* src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
+	USER_NUMBER_HAS_STRING_ALIAS throughout.
+	* src/symtab.c (symbol_make_alias): Remove comment from symtab.c
+	that is repeated in symtab.h.  Improve argument names to make it
+	clear which side of the symbol-string alias pair is which.
+	(symbol_check_alias_consistency): Improve local variable names
+	for the same purpose.
+	* src/symtab.h (struct symbol): Make comments about aliases
+	clearer.
+	(symbol_make_alias): Improve comments and argument name.
+	* src/output.c (token_definitions_output): Update for rename to
+	USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
+
+2009-08-08  Alex Rozenman  <rozenman@gmail.com>
+
+	Convert "misleading reference" messages to warnings.
+	* src/scan-code.l: New function 'show_sub_messages', more
+	factoring.
+	* tests/named-ref.at: Adjust tests.

+
+2009-08-06  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: make update-b4-copyright easier to use
+	* build-aux/update-b4-copyright: In warnings, report line
+	numbers rather than character positions.
+	* cfg.mk (update-copyright-local): Set to update-b4-copyright so
+	that update-copyright runs it.
+	* gnulib: Update.
+
+2009-08-05  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: clean up update-b4-copyright code
+	* build-aux/update-b4-copyright: Do not accept 2-digit
+	UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
+	Don't accept a `[' in a b4_copyright argument.
+	Format code more consistently.
+	Don't assume b4*copyright never occurs.
+
+2009-08-04  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: automate b4_copyright updates.
+	* Makefile.am (update-b4-copyright): New target rule.
+	* build-aux/local.mk (EXTRA_DIST): Add update-b4-copyright.
+	* build-aux/update-b4-copyright: New.
+	* data/yacc.c: Remove stray characters around b4_copyright

+2009-08-04  Joel E. Denny  <jdenny@clemson.edu>
+
+	maint: automate annual package-wide copyright-year update.
+	* .x-update-copyright: New.
+	* Makefile.am (EXTRA_DIST): Remove maint.mk.
+	* bootstrap.conf (gnulib_modules): Add maintainer-makefile and
+	update-copyright.  Remove gnumakefile, which is implied by
+	maintainer-makefile.
+	* cfg.mk (bootstrap-tools): Copy from old maint.mk.
+	* gnulib: Update.
+	* maint.mk: Remove, now copied from gnulib.
+	* examples/extexi: Add missing "(C)" in copyright statement so
+	update-copyright can recognize it.
+	* src/LR0.h: Likewise.
+	* src/print.h: Likewise.
+	* src/print_graph.h: Likewise.
+	* src/gram.c: Add missing comma in copyright statement.

+
+	Fix "make distcheck".
+	* examples/calc++/Makefile.am: Say $(srcdir)/calc.stamp instead
+	of just calc.stamp.
+
+2009-08-01  Joel E. Denny  <jdenny@clemson.edu>
+
+	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.
