        * resolve.c (resolve_component): There is no need to resolve
        the components of a use associated vtype.
        (resolve_fl_derived): Unconditionally generate a vtable for any
        module derived type, as long as the standard is F2003 or later
        and it is not a vtype or a PDT template.
