| Here's a proposed patch to fix one or two POSIX-compliance bugs in Bison.
| * POSIX says that YYDEBUG must be defined to be 0 if the user never specifies
| debugging, but the Bison-generated parser leaves YYDEBUG undefined.
|
| * This is a very minor point, but POSIX doesn't seem to require that
| the user must YYDEBUG to a parenthesized expression, e.g. `#define
| YYDEBUG 0 ? 0 : 1' seems to be allowed. We might as well survive
| such programs while we're at it.
Fine, please, install!
