There are other problems besides the license.  It would have to be
customized to use a different integer type (scm_t_inum).  I'd want to be
able to #include it directly into numbers.c as a static function to
avoid a slow function call through the shared-library PLT.  Also, it's
not particularly well optimized.  It lacks the nice tricks that Niels
recently told me about that are used in GMP.

If these issues were addressed, I'd be open to using it, but for such a
small function, it hardly seems worth the hassle.
