BOOST_HAS_THREADS is defined automatically when _MT is defined; most Windows 
compilers define _MT when their multithreaded runtime library is selected.

Yes, this would work. BOOST_DISABLE_THREADS is a user macro that causes 
BOOST_HAS_THREADS to not be defined, regardless of whether the platform is 
detected to support multiple threads.

The configuration macros are described in
