pardon silly question, but... why, on 64bit machine, P9 uses 32bit ints and
longs?

my impression is, int was supposed to match machine's preferred (best
performance etc.) integeral datatype, and long was supposed to be enough to
hold a pointer? (i.e., sizeof(long) >= sizeof(void*))

Until real software engineering is developed, the next best practice is to
develop with a dynamic system that has extreme late binding in all aspects.
