In libgcj we're using `int' in FileDescriptor.  I don't think we have
cross-platform problems.  However, it wouldn't hurt to change this to
`long'.  I know this has come up before with libgcj, but I don't
remember why we never made a change -- probably because on Windows,
sizeof(int)==sizeof(void*).
