At least at Linux, the -pthread option to gcc causes Boost.Config to define 
BOOST_HAS_THREADS.

Possibly, cygwin's gcc does not recognize -pthread.

Yea, it does not recognize it. Could you please get

http://zigzag.cs.msu.su:7813/working_copy/new/os.jam
http://zigzag.cs.msu.su:7813/working_copy/tools/gcc.jam

place to the appropriate directories in your V2 tree and try again. I've moved 
threading related code from V1, and hopefully it will fix your problem.
