+
+	Use variants to support objects as semantic values.
+	This patch was inspired by work by Michiel De Wilde.  But he used Boost
+	variants which (i) requires Boost on the user side, (ii) is slow, and
+	(iii) has useless overhead (the parser knows the type of the semantic value
+	there is no reason to duplicate this information as Boost.Variants do).
+	
+	This implementation reserves a buffer large enough to store the largest
+	objects.  yy::variant implements this buffer.  It was implemented with
+	Quentin Hocquet.
+	
+	* src/output.c (type_names_output): New.
+	(output_skeleton): Invoke it.
+	* data/c++.m4 (b4_variant_if): New.
+	(b4_symbol_value): If needed, provide a definition for variants.
+	* data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
+	(b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
+	(b4_char_sizeof, yy::variant): New.
+	(parser::parse): If variants are requested, define
+	parser::union_type, parser::variant, change the definition of
+	semantic_type, construct $$ before running the user action instead
+	of performing a default $$ = $1.
+	* examples/variant.yy: New.
+	Based on an example by Michiel De Wilde.
+
+2008-11-03  Akim Demaille  <demaille@gostai.com>
+
+	Parameterize the extraction of semantic values.
+	To make future changes easier, no longer rely on ".TYPE" being the
+	way to get a semantic value.
+	
+	* data/c.m4 (b4_symbol_value): New.
+	Use it.
+	* data/c++.m4, data/yacc.c: Use it.
+	* data/glr.c: Use b4_symbol_value.

+	Say %language is experimental.
+	We're thinking of extending it's effect on output file naming.  See the

+
+2008-10-30  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Always put auxiliary code files in the same dir as other output files.
+	* src/files.c (compute_file_name_parts): When the user specifies
+	--output but not --file-prefix, extract the directory prefix from the

+
+2008-04-23  Eric Blake  <ebb9@byu.net>

+	* tests/output.at (m4_expand): Add workaround for autoconf 2.62.
+	("Output file name: ("): Uncomment test.
+	("Output file name: )"): Likewise.

+
+2008-04-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
+	2.61.  Reported by Juan Manuel Guerrero at
+	<http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
+	* tests/output.at ("Output file name: ("): Comment out test case for
+	now.
+	("Output file name: )"): Likewise.
+
+2008-04-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* GNUmakefile: Update git-version-gen invocation so make dist
+	succeeds.
+
+2008-04-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Update to the current gnulib CVS repository, and fix trigraph handling
+	in Bison.
+	* bootstrap: Update gnulib CVS repository URL.
+	(symlink_to_dir): Encapsulate the code that guarantees the destination
+	directory exists into...
+	(check_dst_dir): ... this new function, and...
+	(cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
+	fail when copying files into lib/uniwidth/.
+	* src/output.c (prepare_symbols): When writing yytname muscles, where
+	symbol names will be encoded in C-string literals, tell quotearg to
+	escape trigraphs.  This used to be the default in gnulib.
+	* tests/regression.at (Token definitions): Because of the change in
+	gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
+	escapes trigraphs in symbol names.  Thus, yytname no longer has
+	trigraphs unnecessarily doubly escaped.  Update test case output.
+	Extend test case to be sure Bison's own error messages will no longer
+	have trigraphs in symbol names unnecessarily escaped once.
+
+2008-04-20  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Fix make dist infinite loop reported by Juan Manuel Guerrero at
+	<http://lists.gnu.org/archive/html/bug-bison/2008-01/msg00009.html>.
+	* .cvsignore: Add .version.
+	* .version.in: New.
+	* bootstrap.conf (gnulib_modules): Add git-version-gen.
+	* configure.ac (AC_CONFIG_FILES): Add .version.
+	* build-aux/.cvsignore: Add git-version-gen.
+
+2008-03-08  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* NEWS (2.3a+): Mention that -g now takes an argument.
+	* doc/bison.texinfo (Bison Options): Reword -W entry a little for
+	consistency.  Update the -g and -x entries now that they take
+	arguments.  Use brackets to indicate optional arguments.
+	* src/getargs.c (usage): Explain the relationship between arguments of
+	long and short options more completely.  Document --defines and -d
+	separately since the former takes an argument but, for POSIX Yacc, the
+	latter does not.
+	(short_options): Let -W take an optional argument like --warnings.
+	(getargs): Sort cases.
+
+2008-02-28  Akim Demaille  <demaille@gostai.com>
+
+	* doc/bison.texinfo: Fix a few typos.
