From what I understand the underlying cause is because 64bit windows
(or more specifically the visual studio C compiler) uses an LLP64
(IL32P64) data model* while most 64bit unix based systems use LP64
The previously linked article on getting a 64bit windows pypy talks
about the size difference for long but doesn't spell out the data model
Hopefully that helps clear up where the underlying issue comes from.
