WARNING: No error rule is defined for exclusive state 'pragma' WARNING: Token 'PPHASH' defined, but not used WARNING: There is 1 unused token
This commit surpresses those warnings by:
Eliminating the PPHASH token, while retaining the t_PPHASH rule so that location information encoded in #line directives is correctly tracked.
