This error is caused by "boost/detail/interlocked.hpp" autodetecting 
_InterlockedDecrement as a compiler intrinsic, which it doesn't seem to be.

If you don't use threads, you can #define BOOST_SP_DISABLE_THREADS to turn 
off shared_ptr's thread support; otherwise, try #defining 
BOOST_USE_WINDOWS_H to make Interlocked* available to shared_ptr.
