the portability issues have to do with the calling convention I
assume.That would be no problem since it would only take minor
alterations in the universal wrapper to port it.How is it possible to
make the lua interpreter call the wrapper function instead of the
actual C function supplying it with C function pointer and args(so
that the wrapper can do the actual calling)?
