/* FIXME: It sure would be nice if we had a way of checking whether
|
|
* or not these objects responded to the messages we're sending them here.
|
|
* We need a way that is independent of whether we have GNUStep objects,
|
|
* NEXTSTEP objects, or GNU objects. We could certainly just use the
|
|
* same trick that the `respondsToSelector:' method itself uses, but I'd hoped
|
