+
+	Factor %FLAG at scan level.
+	* src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
+	definitions and associated rules, replaced by....
+	(PERCENT_FLAG): this new token type, and rule.
+	* src/scan-gram.l (RETURN_PERCENT_FLAG): New.
+	Use it for %debug and %error-verbose.
+
+2009-04-03  Akim Demaille  <demaille@gostai.com>
+
+	Regen.
+	* src/parse-gram.h, src/parse-gram.c: Regen.
+
+2009-04-03  Akim Demaille  <demaille@gostai.com>
+
+	Treat %debug as %define debug.
+	* data/bison.m4 (b4_debug_if): New.
+	* data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c,
+	* data/lalr1.java: Use it instead of b4_debug_flag.
+	* src/getargs.h, src/getargs.c (debug_flag): Remove.
+	* src/output.c (prepare): Don't output it.
+	* src/parse-gram.y: Treat %debug as %define debug.
+
+2009-04-03  Akim Demaille  <demaille@gostai.com>
+
+	Treat %error-verbose as %define error_verbose.
+	This allows to pass -Derror_verbose on the command line.  Better
+	yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
+	ERROR_VERBOSE being defined as false or true.
+	* data/bison.m4 (b4_percent_define_if_define): Instead of relying
+	on b4_percent_define_ifdef, for does not check the defined value,
+	but only whether the symbol is defined, rely on
+	b4_percent_define_flag_if, so that a value of "false" is processed
+	as a false.
+	If not defined, define the flag to "false".
+	(b4_error_verbose_if): New.
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
+	b4_error_verbose_flag.
+	* src/getargs.h, src/getargs.c (error_verbose_flag): Remove.
+	* src/output.c (prepare): Don't output it.
+	* src/parse-gram.y (%error-verbose): Treat as %define error_verbose.

+2009-04-03  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Fix strange %define locations for default values.
+	Reported by Akim Demaille at
+	<http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
+	and discussed again starting at
+	<http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
+	* data/bison.m4 (b4_percent_define_default): Leave syncline blank
+	because location information is bogus.
+	Use angle brackets to delimit fake file name because square brackets
+	look like underexpanded m4.  Choose a better fake file name.
+	Use negative line numbers.
+	* src/muscle_tab.c (muscle_percent_define_default): Likewise.
+	* src/location.c (location_print): If line for a boundary is negative,
+	only print that boundary's file name.
+	* src/location.h: Document that.
+	* tests/skeletons.at (%define Boolean variables: invalid skeleton
+	defaults): Update output.
+
+2009-04-03  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Pacify ./configure --enable-gcc-warnings.
+	* Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
+	in lib won't compile with it.
+	* src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
+
+2009-03-31  Akim Demaille  <demaille@gostai.com>
+
+	bootstrap: --help to stdout.
+	* bootstrap (usage): Don't send --help to stderr.
+	Use a here doc instead of a long string.
+
+2009-03-31  Akim Demaille  <demaille@gostai.com>
+
+	bootstrap: README-hacking no longer exists
+	* bootstrap (checkout_only_file): Set to HACKING.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+	doc: merge HACKING and README-hacking.
+	Two files is confusing.
+	Reported by Alexandre Duret-Lutz.

+	Reported by Ralf Wildenhues and Alexandre Duret-Lutz.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+	lalr1.cc: avoid GCC 4.3 warnings.
+	GCC 4.3 now warns about "a || b && c" and asks for explicit
+	parentheses.
+	Reported by Alexandre Duret-Lutz.
+	* data/location.cc: Update copyright years.
+	(Position::operator==): Use parens to make precedence explicit.
+	Compare lines and columns first, as they are more likely to be
+	different, and they are faster to compare.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+	gnulib: update.

+
+2009-03-02  Akim Demaille  <demaille@gostai.com>
+
+	Use locations in the variant example.
+	Yes, this obfuscates the point of this example, variants only.

+	Remove the "b4_variant_if" parts, as variant.hh is loaded only if
+	needed.
+	* data/lalr1.cc: No longer invoke b4_symbol_constructor_define and

+
+	Dub symbol_type_base as a public type.
+	* data/c++.m4 (b4_public_types_declare): Now define
+	symbol_type_base and symbol_type.
+	(b4_public_types_define): New.
+	In both cases, the definitions are taken verbatim from lalr1.cc.
+	* data/lalr1.cc: Adjust.
+
+2009-03-02  Akim Demaille  <demaille@gostai.com>
+
+	b4_public_types_declare.

+
+2009-02-19  Akim Demaille  <demaille@gostai.com>
+
+	Make yyparser::error public.
+	* data/lalr1.cc: here.
+	There is no good reason to keep it private (and it is convenient
