I didn't see this come up anywhere...

Is there a problem with declaring the structure pointer as an extern
and then doing the sizeof thang?  As:

	extern struct foo *Foo;

	sizeof Foo->member

This requires no data allocation which was the original gripe, eh?

Pax, Keith

Ps, This casting NULL to some structure pointer then grabbing a member
from it FOR ANY REASON seems dubious, at best, to me.  $.02.
