Boost in C++11 should use the std:: facilities.

Boost provides existing practice and reference implementations to aid
in the standardization process. But we don't actually realize the
benefits of standardizing Boost components if we never move off our
own reference implementations. If there is a problem with a vendor's
implementation of these std:: facilities, we should help that vendor
get the implementation right.
