        * typeck.c (structural_comptypes): No need to check
        resolve_typename_type return value here.
        * cp-tree.h (TYPENAME_IS_RESOLVING_P): New.
        * pt.c (resolve_typename_type): Follow typename typedefs.  Return
        original type rather than error_mark_node in case of failure.
        * parser.c (cp_parser_nested_name_specifier_opt): Adjust
        resolve_typename_type result check.
        (cp_parser_direct_declarator, cp_parser_head,
        cp_parser_constructor_declarator_p): Likewise.
