I have another question: Didn't Greg Harvey try to change guile't bignum
interface to use gmp (The GNU Multiple Precision Arithmetic Library)? In
gmp these functions are already implemented.
Maybe it would make more sense to finish Greg's changes and have guile use
gmp. Currently, after a couple of years, gmp seems to be under active
development again (see http://www.swox.com/gmp/). According to their
web page the release of version 3.0 is scheduled for march.
