        * c-parser.c (c_parser_pragma): Add IF_P argument, pass it down
        where needed.

        c_parser_parameter_declaration, c_parser_compound_statement_nostart,

        Adjust c_parser_pragma callers.
        (c_parser_statement_after_labels): Likewise.  Adjust c_parser_cilk_for
        caller.

        c_parser_statement.
