+
+	* data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
+	(Parser::parse): here.
+	Adjust: nerrs and errstatus is now replaced by...
+	(Parser::nerrs_, Parser::errstatus_): New.

+
+	* config/announce-gen, Makefile.cfg: New.
+	* Makefile.am: Adjust.
+	* GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
+	keeping local WGET and WGETFLAGS modifications from Paul Eggert.

+
+	When reducing initial empty rules, Bison parser read an initial
+	location that is not defined.  This results in garbage, and that
+	affects Bison's own parser.  Therefore we need (i) to extend Bison
+	to support a means to initialize this location, and (ii) to use
+	this CVS Bison to fix CVS Bison's parser.
+
+	* src/reader.h, reader.c (epilogue_augment): Remove, replace
+	with...
+	* src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
+	* src/parse-gram.y: Adjust.
+	(%initial-action): New.
+	(%error-verbose): Since we require CVS Bison, there is no reason
+	not to use it.
+	* src/scan-gram.l: Adjust.
+	* src/Makefile.am (YACC): New, to make sure we use our own parser.
+	* data/yacc.c (yyparse): Use b4_initial_action.

+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo: Don't promote stdout for error messages.

+
+	* data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
+	From Alexandre Duret-Lutz.

+
+	* data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
+	Use them.

+
+	Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
+	error recovery loops.  This patch is based on
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+	Also, augment the similarity between lalr1.cc and yacc.c.
+	Note: the locations of error recovery rules are not correct yet.
+
+	* data/lalr1.cc: Comment changes to augment the similarity between
+	lalr1.cc and yacc.c.
+	(YYERROR): Goto to yyerrorlab, not yyerrlab1.
+	(yyerrlab1): Remove, but where it used to be (now the bottom part of
+	yyerrlab), when hitting EOF, pop the whole stack here instead of
+	merely falling thru the default error handling mechanism.
+	(yyerrorlab): New label, with the old contents of YYERROR,
+	plus the following change: pop the stack of rhs corresponding
+	to the production that invoked YYERROR.  That is how Yacc
+	behaves (required by POSIX).
+	* tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
+	fail.

 	Tune local.at so that people can "autom4te -l autotest calc.at -o
