This code makes me cry... I know Visual Studio won't like it either.
Cephes is a constant source of problems . As I mentioned a couple of
months ago, I think the only solution is to rewrite most of
scipy.special, at least the parts using cephes, using for example boost
algorithms and unit tests. But I have not started anything concrete -
Pauli did most of the work on scipy.special recently (Kudos to Pauli for
consistently improving scipy.special, BTW)

cheers,

David
