+       * 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.
