	* c-parse.in (designator): Enable designated initializers if ObjC.
	(objcmessageexpr): Remove references to objc_receiver_context.
	* objc/objc-act.h (objc_receiver_context): Remove decl.
	* objc/objc-act.c (objc_receiver_context): Remove.
	(lookup_objc_ivar): Test objc_method_context instead of
	objc_receiver_context.
