Any exceptions to the rule should follow the same logic that 
Boost.Threads does.  When BOOST_HAS_THREADS is not defined all of the 
Boost.Threads headers detect this and issue a #error directive.  This 
way the error occurs only if you attempt to use Boost.Threads with a 
compiler/platform that's not defined to support threading.
