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.
