Does it still not work with BOOST_SP_DISABLE_THREADS or 
BOOST_SP_USE_PTHREADS defined? If so, it's a general problem, not caused by 
the platform-specific atomics; it could be a compiler backend bug, and 
should probably be reported to the GCC Bugzilla. Can you try a 4.x g++? It 
might have even been fixed.
