        * c-parser.c (c_token_is_qualifier,
        c_parser_next_token_is_qualifier): New.
        (c_parser_declaration_or_fndef, c_parser_struct_declaration):
        Improve error message on specs->tagdef_seen_p.
        (c_parser_struct_or_union_specifier): Improve error recovery.
        (c_parser_declspecs): Move exit condition on C_ID_ID early.
        Reorganize exit condition for C_ID_TYPENAME/C_ID_CLASSNAME
        using c_parser_next_token_is_qualifier; extend it to cover
        a ctsk_tagdef typespec and !typespec_ok in general.
