No, rolling it back was quite the thing to do, I missed the fact that we already have a method that serves the same purpose. Actually, I quite agree about the dangers of mixing pointers and integers. In this case, however, the method (the actual one is -windowDevice:) takes the GNUstep window number as an argument and returns the backend dependent window representation, which in the case of X11 is a 32 bit integer, but some hypothetical backend could potentially use an arbitrary data structure. So using a void* return type and requiring the caller to cast it appropriately is probably the way to go.
