I suppose I need to do some more homework then.
If GNU Classpath is used without modification for
numerous VM's, then great!  Ultimately, what I am
looking for is what the native calls do, which _will_
become VM-dependent at some point.  As long as they
return the same result to the class library, however,
there should be no reason to have to change that library.

Well, maybe I don't either.  Perhaps I am demonstrating my
ignorance of part of this subject :) here.
