Why?

This is an implementation detail which can differ on OS X and GNUstep. As
far as I understand it, it's only needed inside CoreBase/Core Foundation.
Why would you need to even determine if something is a small pointer in
another library?

Luboš can correct me if I'm wrong, but you don't need to know whether the
pointer is a "small object" outside very small amount of runtime code and
toll-free bridging-related code, which will be implemented in core GNUstep
libraries; and for any binary compatibility you will not and should not
need to know this implementation detail about the kind of object that is
stored in a pointer.

Right? :-)
