While there's no actual reference to changes in unexelf, that I can see, in the ChangeLog, it seems that synching that up with Emacs 20.3 lets XEmacs compile and run peachy keen. I suppose I could simply diff out what's changed and pick out the bits which helped this particular problem, but I think that there were enough changes that maybe somebody should just look it over and see what other platforms might benefit from it.
