 Message        <Context> the qualifier for "<name>" is not a struct
                or union.

 Description    In certain modes, the compiler will allow the left
                operand of a struct/union member reference to be
                certain types other than a struct or union type.  In
                these cases the compiler will issue a warning that
                this non-standard syntax is being accepted.

 User Action    Modify the left operand to be a struct or union type.
