Hmmm.
See, i've never actually run into problems with the way i do it now
(vtables) in real code.
I only noticed the problems when i started trying to get every single
test in virtfunc.exp to pass.
Is using typeinfo when available (if you expect that to be more
robust), and falling back on the vtables-approach an option?
