I haven't had a chance to look at the changes in cdd_both_reps.c, but I
wonder if they really need to be in cddlib, or if this just seemed
easiest at the time. Anyway, it's on my list of things to think about;
polymake, which I'm in the process of packaging, also embeds a copy of
cddlib; in that case it needs to link to the library compiled two
different ways: floating point and gmp arithmetic.

Alas, no definite schedule from my end.
