  Why an int and not a long?

Please resend this message in 1991.  :-)

We have some plans of allowing a greater range without making the mpz
object much larger.  The idea is that allocation does not need very fine
granularityu, so we can steal some of the (32) bits from the _mp_alloc
field.  But _mp_size needs to be exact, so the stolen bits alloc field
will go to to _mp_size.
