    * parser.c (cp_parser_new_type_id): Early return error_mark_node
    if the cp_parser_type_specifier_seq call has type_specifier_seq.type
    error_mark_node; tidy.
    (cp_parser_new_expression): Always initialize nelts to NULL_TREE to
    avoid uninitialized warnings.
    (cp_parser_init_declarator, cp_parser_late_parse_one_default_arg):
    Call cp_parser_skip_to_end_of_statement if cp_parser_initializer
    returns error_mark_node.
