        FIXME: Bison should warn if a semicolon seems to be necessary
        here, and should omit the semicolon if it seems unnecessary
        (e.g., after ';', '{', or '}', each followed by comments or
        white space).  Such a warning shouldn't depend on --yacc; it
        should depend on a new --pedantic option, which would cause
        Bison to warn if it detects an extension to POSIX.  --pedantic
        should also diagnose other Bison extensions like %yacc.
        Perhaps there should also be a GCC-style --pedantic-errors
        option, so that such warnings are diagnosed as errors.  */
