In the following source file, errors are not properly flagged for attempts
to give default arguments within (unary) operator declaration formal argument
lists.  Also, a "syntax error" *is* reported for (apparently) no reason.

b062 had missed error(s) as follows:
	14: int operator + (st st1 = st_object);		// ERROR
	17: int operator - (st st1 = st_object);		// ERROR
	20: int operator & (st st1 = st_object);		// ERROR
	23: int operator * (st st1 = st_object);		// ERROR
	25: int operator ~ (st st1 = st_object);		// ERROR
	27: int operator ! (st st1 = st_object);		// ERROR
	29: int operator ++ (st st1 = st_object);		// ERROR
	31: int operator -- (st st1 = st_object);		// ERROR
	33: int operator ( ) (st st1 = st_object);		// ERROR
b062: FAILED
