I don't see why it should be that difficult.

If sizeof becomes an intrinsic that is called at runtime to determine
the pointer size (probably stored in some global or read from a
configuration register), than the problem is solved. If the types'
sizes change too, this intrinsic could accept a parameter (enum?) with
the type of the type.
