No, Jeff is right;  I did propose having two fields, an int and
a RawData.  I also consider what you're proposing:  A single
RawData field, and then cast to/from int on Posix/Windows systems.
That would be more efficient, but it may be uglier and in theory
less portable.  I.e. there may be architectures where you can't
safely convert an int to a (void*) and back again.  (However, if
we have natFileDescriptorStdio, such platforms could use that.)

I guess I would have a slight preference for using a single field
rather than two.
