        * parser.c (cp_parser_maybe_commit_to_declaration,
        cp_parser_check_condition_declarator): New.
        (cp_parser_simple_declaration): Use the first above.
        (cp_parser_condition): Use both the above; enforce
        [stmt.stmt]/2 about the declarator not specifying
        a function or an array; improve error-recovery.
