Yes, but be aware that I'm developing a POSIX-like environment that  
runs over classic Mac (MacRelix[1]), which overrides MSL and adds its  
own library calls as necessary.  It's also conceivable that MacRelix's  
userspace library might eventually replace MSL completely.

Not yet, but I intend to implement pthreads in the future for user  
programs in MacRelix.

If you prefer to just remove the line defining BOOST_HAS_THREADS  
instead, that's fine.  I don't have strong feelings about it.
