The semantics of ARC are not complicated when it comes to ivars. They simply do a retain of the new value then a release of the old one, unless the pointer is marked as __unsafe_unretained. If we have public ivars in GNUstep headers that are intended to hold object references that are not retained, then an assignment to them from ARC code will break things.
