* c-common.h (struct c_common_identifier): Remove rid_code field.

	(C_RID_CODE): Use ->node.rid_code instead of ->rid_code.

	* c-typeck.c (constructor_designated): New local flag.
	(struct constructor_stack): Add "designated" field to match.
	(start_init): Clear it.
	(really_start_incremental_init, push_init_level): Push and
	clear it.
	(pop_init_level): Pop it.
	(set_designator): Set it.

	(pop_init_level): Suppress "missing initializer" warnings if
	constructor_designated is true.
	(process_init_element): Suppress warning about union
	initialization under traditional C, if constructor_designated
	is true.

	* intl/loadmsgcat.c (INTTYPE_SIGNED, INTTYPE_MINIMUM,
	INTTYPE_MAXIMUM): Clone from system.h.
	(_nl_load_domain): Use them when testing for overflow of size_t.
	Cast result of sizeof to off_t to compare to st_size value.
	Move side effects out of conditional for comprehensibility.

	* testsuite/gcc.dg/20011021-1.c: New test.
