Right: the normal invocation is:

#ifdef BOOST_HAS_LONG_LONG
// (unsigned) long long specialisation here
#elif defined (BOOST_HAS_MS_INT64)
// (unsigned) __int64 specialistion here.
#endif

Note that the current code will likely break on recent msvc versions because 
"long long" and __int64 are the same type, but you have specialisations for 
both :-(

HTH, John.
