I have not looked at the respective code yet (short of time right now)
but the names of those functions suggests that they might be looking at
those variables not as much as Scheme values but rather as internals
related to the operation of the Scheme interpreter.  If that guess is
correct, using SCM_UNPACK would likely better convey the kind of action
here (and allow access as a bit pattern/integer/whatever).
