AFAICT, it is not strictly needed. If not available, the compiler will
generate wrapper functions rather than thunking half-functions when
having to adjust the this-pointer in case of multiple inheritance. If
the virtual function has varargs, this is not possible, and the
compiler will be sorry.

I guess it is not difficult to provide MI thunks; it just hasn't been
done.

Martin
