heitbaum c7bd01c62a yyerror: update to POSIX standard ...

To comply with the latest POSIX standard, in Yacc compatibility mode
(options `-y`/`--yacc`) Bison now generates prototypes for yyerror and
yylex.  In some situations, this is breaking compatibility: if the user
has already declared these functions but with some differences (e.g., to
declare them as static, or to use specific attributes), the generated
parser will fail to compile.  To disable these prototypes, #define yyerror
(to `yyerror`), and likewise for yylex.
