        * cp-tree.h (CLASSTYPE_READONLY_FIELDS_NEED_INIT): Check that
        lang_type structure exists before accessing field.
        (SET_CLASSTYPE_READONLY_FIELDS_NEED_INIT): New macro.
        (CLASSTYPE_REF_FIELDS_NEED_INIT): Similar.
        (SET_CLASSTYPE_REF_FIELDS_NEED_INIT): New macro.
        * class.c (check_field_decls): Use new macros.
        * typeck2.c (process_init_constructor): Remove redundant check for
        existence of lang_type structure.
