I'm not sure how restrictive this would be for you but perhaps you could try statically linking the runtime and mfc libraries rather than dynamically linking them?
I would suggest that the reverse is preferable: dynamically link the boost.thread library. If you must statically link boost.thread, it might be worth trying putting namespace boost { void tss_cleanup_implemented() {} } in your DLL's code. This should avoid linking in the problematic part of the boost library (though I haven't tried it). You will then need to ensure that every thread that uses boost.thread facilities (especially boost::thread_specific_ptr) and is not started with boost::thread calls boost::on_thread_exit() when it exits.
