Unneeded since long long is guaranteed to be at least 64-bit.

I don't think that using PyLong_FromLong() for small values on 32 bit platforms provides speed-up, but if it does that should be done in PyLong_FromLongLong().
Moreover AFAIK long is 32 bit on 64 bit Windows, so that condition is not compiled out.
