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.
