[issue37170] Wrong return value from PyLong_AsUnsignedLongLongMask on PyErr_BadInternalCall

Aaaah, I didn't notice that the function returns unsigned *long long*, sorry :-)

Which platform is impacted? Windows 64-bit? Does it mean that we have zero unit test on this function? Or does it mean that (unsigned long)-1 is compiled correctly as (unsigned long long)-1 on Windows 64-bit? Is "long long" 8 bytes long and "long" 4 bytes long on Windows 64-bit?
