Well, I did a local test removing the feature, the lib itself builds but 
the test fails massively, so I think it's probably safer not to touch it 
and assume it's not supported. Site stuck with 3.xx should probably 
stick to old version of boost I guess.
Specially considering I have been using boost build only when I really 
had to and still haven't found its documentation.
