+       * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
+       * data/c.m4 (YYPUSH): New.
+       (b4_push_if): New macro.  Use it instead of #ifdef YYPUSH.
+       * src/getargs.c (push_parser): New var.
+       * src/getargs.h (push_parser): New declaration.
+       * src/output.c (prepare): Add macro insertion of `push_flag'.
+       * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
+       (prologue_declaration): Parse %push-parser.
+       * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
+       * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
+       list of removed lines from the traces observed.
+       (AT_CHECK_CALC_LALR): Added push parser tests.

+
+       * NEWS: Version 2.3a.
+       * configure.ac (AC_INIT): Likewise.
+
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
+       "#define YYSTYPE int" that caused "make maintainer-check" to fail
+       due to header ordering dependencies.  I don't know why the #define
+       was there.
+
+       Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
+       runtime cost when YYDEBUG is not defined, and so that some tests
+       that used to fail now work.  Problem and initial suggestion by
+       Paolo Bonzini.
+       * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
+       * data/glr.cc (b4_parser_class_name):
+       Initialize yycdebug_ only if YYDEBUG.  Also, initialize yydebug_.
+       (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
+       (yydebug_) [YYDEBUG]: New member.
+       (yycdebug_): Now defined only if YYDEBUG.
+       * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
+       (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
+       (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
+       if YYYDEBUG.
+       (debug_stream, set_debug_stream, debug_level, set_debug_level):
+       Define only if YYDEBUG.
+       * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
+       set_debug_level.
+       * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
+       * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
+       AT_CHECK_CALC_GLR_CC that are working now.
+
+2006-09-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
+       We don't need them in glr.cc, and glr.c defines them.
+       Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
+       assumes that defining it to anything is the same as defining
+       it to 1.  Problem reported by Paolo Bonzini.

        * data/c.m4 (b4_null, b4_case): Define.
