[boost] Status of (boost) lockfree?

I decided to give the lockfree library that's currently in the review queue a try. On MSVC 9.0, I'm getting this error: boost\lockfree\detail\cas.hpp(129) : error C2440: 'reinterpret_cast' : cannot convert from 'const boost::uint64_t' to 'LONGLONG' The compiler then continues to say: Conversion is a valid standard conversion, which can be performed implicitly or by use of static_cast, C-style cast or function-style cast Am I missing a configuration macro, or is this a valid compile error?
