Considering the package or... whatever, is using unsigned long long
then you might want to use unsigned with the MSVC-specified type as
well, i.e.: "typedef unsigned __int64 ULONGLONG;". Another approach is
"typedef unsigned hyper int ULONGLONG;". hyper specifies according to
MSDN a 64-bit integer that can be declared as either signed or
