Are you sure you meant to type "ILP64"? If I understand the above document correctly, Microsoft chose the LLP64 model. Under Windows 64, int and long are both 32 bits, while long long and pointer are 64 bits. int_t<64>::least would need to give "long long" or "__int64" under 64-bit Windows. Microsoft seems to prefer __int64 in their documentation and system headers.
