re PR c++/13092 (Accepts invalid pointer-to-member conversion)

        PR c++/13092
        * init.c (build_offset_ref): Build SCOPE_REF with non-null
        TREE_TYPE for non-dependent names.
        * pt.c (type_dependent_expression_p): Handle SCOPE_REF with
        unknown_type_node as its TREE_TYPE.
        * cxx-pretty_print.c (pp_cxx_unqualified_id): Handle BASELINK.
        * error.c (dump_decl) <SCOPE_REF case>: Use pp_expression.
        (dump_expr) <SCOPE_REF case>: Likewise.
