We already do; it is documented in gcj.texi as part of CNI.
That said, I'm leery of adding magical methods to it to implement
pointer math.  First, there are the security model considerations.
Second, why not just use CNI in this situation?  That's what it is
there for, and it isn't like code using RawData extensions would be
portable Java anyway.
