For PEP 456 it would be useful to have PY_UINT64_T on 32bit Windows. Does anybody see a problem with Victor's idea? I like it.

Victor wrote in

To support Windows 32 bit, the following code in PC/pyconfig.h can be modified to use __int64 or _W64: see ssize_t definition below in the same file.

#ifndef PY_UINT64_T
#define HAVE_UINT64_T 1
#define PY_UINT64_T unsigned PY_LONG_LONG

Fine by me

It seems no patch is needed to get PY_UINT64_T on 32bit Windows:

>>> import sys
>>> sys.version
'3.4.0a4+ (pep-456:f0a7e606c2d0, Oct 29 2013, 19:24:12) [MSC v.1600 32 bit (Intel)]'
>>> sys.maxsize
>>> sys.hash_info
sys.hash_info(width=32, modulus=2147483647, inf=314159, nan=0, imag=1000003, algorithm='siphash24', hash_bits=64, seed_bits=128)

Yes, it should be taken care of already, because of this in PC/pyconfig.h:

#ifdef MS_WIN32

That defines the symbol triggering the PY_UINT64_T define shown in the original message in this issue.
