Okay, maybe "rely" was the wrong word to use. Current implementation of
BigInt.pmc uses GMP if it's available, else it throws exceptions that
there is no bug number library present to implement the behavior. Same
is true of the unicode charset and ICU. We don't require ICU or GMP to
build parrot, but we don't implement these behaviors without them.
Question is: Are we going to do this same thing for BigNum (use a
library if present, throw sane exceptions otherwise), or are we going to
roll our own BigNum implementation?
