        * parser.c (cp_parser_labeled_statement): Return nothing.  Do
        not take in_statement_expr and in_compound as arguments.  Rename
        to cp_parser_label_for_labeled_statement.  Parse only the label,
        not the statement.
        (cp_parser_statement): Parse the statement of a labeled-statement
        from here, using tail recursion.
