Casting of a local pointer-to-member variable

[Chandra Chavva]

As per ISO/IEC 14882:1998(E) 5.3.1.3 show &(qualified-id) does not form
an expresion of the type "pointer to member", but compiler does not warn 
about it.

The following patch fixes this problem. Please let me know it is okay to 
apply.

Thanks
Chandra

        * semantics.c (finish_parenthesized_expr): Call resolve_offset_ref()
        to give appropriate error message if the qualified_id of a
        pointer-to-member is enclosed in parenthesis.
