Worse than that:  during a rather arcane discussion in comp.std.c I read that
pointers to different objects may be different sizes.  Forgetting the
LONG/SHORT NEAR/FAR perversion of Intel memory models,  does anyone know how
widespread this kind of implementation is and what are the foremost systems
involved?
