+
+ Port to GCC 2.95. First two problems reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+ * src/parse-gram.y (symbol_declaration): Don't put statements
+ before declarations; it's not portable to C89.
+ * src/scan-code.l (handle_action_at): Likewise.
+
+ * src/scan-code.l: Always initialize braces_level; the old code
+ left it uninitialized and therefore had undefined behavior.
+
+ Don't attempt to redefine 'assert', since it runs afoul of
+ systems where standard headers (mistakenly) include <assert.h>.
+ Instead, define and use our own alternative, called 'aver'.
+ * src/reader.c: Don't include assert.h, since we no longer
+ use assert.
+ * src/scan-code.l: Likewise.
+ * src/system.h (assert): Remove, replacing with....
+ (aver): New function, taking a bool arg. All uses changed.
+ * src/tables.c (pack_vector): Ensure that aver arg is bool,
+ not merely an integer.

+
+ * 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.
+

+
+ * 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.
