+       * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
+       for portability to K&R hosts.  Fix typo: signed char is guaranteed
+       only to 127, not to 128.
+       * data/glr.c (yysigned_char): New type.
+       * data/yacc.c (yysigned_char): Likewise.
+       * tests/regression.at (Web2c Actions): signed char -> yysigned_char.

+
+       * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
+       true due to limited range of data type" warning from GCC.
+
+       * data/c.m4 (b4_token_defines): Protect against double-inclusion
+       by wrapping enum yytokentype's definition inside #ifndef
+       YYTOKENTYPE.  This undoes a bug I introduced on 2002-10-12.

+
+       * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
+       Un yy- yyrhs to avoid the name clash with the global YYRHS.

+       * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.

+       Let nondeterministic skeletons be usable with deterministic
+       tables.
+
+       With the patch, GAWK compiled by GCC without -O2 passes its test
+       suite using a GLR parser driven by LALR tables.  It fails with -O2
+       because `struct stat' gives two different answers on my machine:
+       88 (definition of an auto var) and later 96 (memset on this var).
+       Hence the stack is badly corrumpted.  The headers inclusion is to
+       blame: if I move the awk.h inclusion before GLR's system header
+       inclusion, the two struct stat have the same size.
+
+       * src/tables.c (pack_table): Always create conflict_table.
+       (token_actions): Always create conflict_list.
+       * data/glr.c (YYFLAG): Remove, unused.

+
+       * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
+       (O0FLAGS): New.
+       (VALGRIND, GXX): New.
+       * tests/atlocal.in (CFLAGS): Use O0FLAGS.
+       * tests/bison.in: Run $PREBISON a pre-command.
+       * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
+       (maintainer-check-g++): New.
+       * Makefile.am (maintainer-check): New.

+       Tweak some trace messages to match yacc.c's.

        GLR parsers sometimes raise parse errors instead of performing the
