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 http://bugs.python.org/issue19183#msg201629:
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 #if SIZEOF_LONG_LONG == 8 #define HAVE_UINT64_T 1 #define PY_UINT64_T unsigned PY_LONG_LONG #endif #endif

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 2147483647 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 ... #define SIZEOF_LONG_LONG 8
That defines the symbol triggering the PY_UINT64_T define shown in the original message in this issue.

Is there any more work needed on this or can it be closed? Please note the reference to #17884 in .
