+	(token_number_t, item_number_as_token_number)
+	(token_number_as_item_number, muscle_insert_token_number_table):
+	Rename as...
+	(symbol_number_t, item_number_as_symbol_number)
+	(symbol_number_as_item_number, muscle_insert_symbol_number_table):
+	these, since it is more appropriate.
+
+2002-05-26  Akim Demaille  <akim@epita.fr>
+
+	* tests/calc.at (AT_CHECK_CALC): Adjust: there are now additional
+	`Error:' lines.
+	* data/bison.simple (yystos) [YYDEBUG]: New.
+	(yyparse) [YYDEBUG]: Display the symbols which are popped during
+	error recovery.
+	* tests/regression.at (Web2c Actions): Adjust: yystos is output now.
+
+2002-05-25  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Debugging): Split into...
+	(Tracing): this new section, its former contents, and...
+	(Understanding): this new section.
+	* src/getargs.h, src/getargs.c (verbose_flag): Remove, replaced
+	by...
+	(report_flag): this.
+	Adjust all dependencies.
+	(report_args, report_types, report_argmatch): New.
+	(usage, getargs): Report/support -r, --report.
+	* src/options.h
+	(struct option_table_struct): Rename as..,
+	(struct option_table_s): this.
+	Rename the `set_flag' member to `flag' to match with getopt_long's
+	struct.
+	* src/options.c (option_table): Split verbose into an entry for
+	%verbose, and another for --verbose.
+	Support --report/-r, so remove -r from the obsolete --raw.
+	* src/print.c: Attach full item sets and lookaheads reports to
+	report_flag instead of trace_flag.
+	* lib/argmatch.h, lib/argmatch.c: New, from Fileutils 4.1.

+2002-05-24  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+	and Paul Eggert  <eggert@twinsun.com>
+	
+	* data/bison.simple (yyparse): Correct error handling to conform to
+	POSIX and yacc.  Specifically, after syntax error is discovered,
+	do not reduce further before shifting the error token.
+	Clean up the code a bit by removing the labels yyerrdefault,
+	yyerrhandle, yyerrpop.
+	* NEWS: Document the above.
+
+2002-05-20  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* data/bison.simple (yyr1): Don't use yy_token_number_type as element
+	type; it isn't always big enough, since it doesn't necessarily
+	include non-terminals.
+	(yytranslate): Expand definition of yy_token_number_type, so that 
+	the latter can be removed.
+	(yy_token_number_type): Remove, only one use.
+	* data/bison.c++ (r1_): Parallel change to yyr1 in bison.simple---
+	don't use TokenNumberType as element type.
+	
+	* tests/regression.at: Modify expected output to agree with change
+	to yyr1 and yytranslate.
+	
+2002-05-13  Florian Krohm  <florian@edamail.fishkill.ibm.com>
+
+	* src/reader.c (parse_action): Use copy_character instead of
+	obstack_1grow.
+
+2002-05-13  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (Token definitions): Prototype yylex and
+	yyerror.
+
+2002-05-12  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* src/scan-skel.l: Correct off-by-one error in handling of __oline__.
+	* data/bison.simple (b4_sint_type, b4_uint_type): Correct to reflect
+	32-bit arithmetic.
+	* data/bison.c++ (b4_sint_type, b4_uint_type): Ditto.

 	* tests/synclines.at: Be sure to prototype yylex and yyerror to
