FWIW I'm getting an error on the develop branch using g++ 4.4 in C++0x mode:

../../boost/optional/optional.hpp:954: error:
‘boost::optional<T>::optional(boost::optional<T>&&)’ cannot be
defaulted
../../boost/optional/optional.hpp:1031: error: ‘boost::optional<T>&
boost::optional<T>::operator=(boost::optional<T>&&)’ cannot be
defaulted

g++ 4.6 doesn't have this issue.
