Perhaps I've missed something, but it doesn't seem immediately obvious
to me that a straight-forward wrapping of C's fgetpos/fsetpos is
desirable. Not that it is a bad thing, but I don't see why this
criterion should motivate any particular design decision. Does having a
straightforward wrapping further any of the guiding principles listed in
the introduction of the report? Furthermore, does having a
straightforward wrapping further those guiding principles better than or
more than a design decision which does not result in a straightforward
wrapping of fgetpos/fsetpos?

Hopefully, you can just whip off an answer that should have been obvious
to me.
Regards,
Jon
