Below is an example of how to use the `foreign action' FCall feature found
in the current sources.  It avoids wrapping scalars in Objects, and
thus avoids the problem you're having.

Note that unlike C, that `long' in Java is fixed at 64 bits.
That's why use of the addLongLong:.  I fixed some things related to long
in today's snapshot, so if you're using longs, be sure to grab it.
