Yes, this was the idea.

Thanks for the links. Unfortunately, we cannot really translate these 
codes, due to license issues. (It's LGPL, which is incompatible with BSD.)

However, based on a quick look, it appears that they are straightforward 
implementations of the algorithm from Abramowitz & Stegun chapter 22.18. 
These should be straightforward to implement (using Cython indeed seems 
like a good idea here).
