Thanks for the info, the patches below are going into cvs now, one thing to 
note: you must have built the compiler with --enable-threads, otherwise 
Boost threading support will still be forced off (if the std lib isn't 
thread safe, neither will Boost be whatever you do), but of course you knew 
that anyway :-)
