Actually, my bad - this patch lacks a related part which I have in my local 
tree.  In the new vc, vc-call is a macro, so vc-hooks needs to be loaded for 
ediff-vers.el (ediff-vc-latest-version) at compile time to avoid it being 
miscompiled.

I posted this patch in September but don't remember exactly why I haven't 
applied it, possibly because I don't remember seeing a reply to my post back 
then: http://calypso.tux.org/pipermail/xemacs-beta/2007-September/012194.html

Ok to apply this along with the rest of the previous patch?
