Yup. There are other complexities with virtual bases as well (which
it sound like Java does use for interfaces). There need to be "vcall
offsets" in the vtables to deal with virtual function calls given a
pointer to the interface type. This code, more than the mangling
code, will be difficult to share; I think the Java folks will most
likely have to recode it. However, I don't think it will be too hard
to get right, especially given the C++ front-end as a model.
