It is also confusing that numpy has two constructors that produce 32-bit integers on 32-bit platforms and 64-bit integers on 64-bit platforms, but neither of these constructors is called "long".  Instead, they are called numpy.int_ and numpy.intp. 

I'm pretty sure that numpy.int_ will produce a 32 bit type in Windows64 -- because a long on Windows64 is 32 bit (at least with the MS compiler).

Which sucks, I'm pretty amazed that python went with "platformlong" for it's int, rather than "32 bit int" or "64 bit int". Sigh.
