+       * data/bison.simple (yystos) [YYDEBUG]: New.

+
+       * 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.

+       
+       * 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.

        * src/scan-skel.l: Correct off-by-one error in handling of __oline__.
