PyPy is not available for 64-bit Windows.
How odd. sys.maxint on macOS and Fedora is (2**63)-1 not (2**31)-1.
That's because MacOS and Fedora are not Windows.
Do you why windows is unique in this respect?

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
(I32LP64).
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
explicitly.
Hopefully that helps clear up where the underlying issue comes from.
