OK, understood. Then, we have the somewhat unfortunate situation that in 
GCC environments
Boost.Build links / does not link Pthreads depending on whether the 
threading parameter is multi / single,
whereas Boost.Config does not reflect this situation in any manner!

As most GCC environments (somebody correct me if I'm wrong) are nowadays 
multithreaded,
would it make sense to change GCC Boost.Build bjam rules so that  
threading=simple results in
BOOST_DISABLE_THREADS being defined?
