Hi,

I've noticed that my Boost.Log tests on MSVC are failing massively. The build 
log hints that Boost.Thread might be the culprit, and its tests are also 
failing on MSVC with the following error:

..\boost/thread/future.hpp(1127) : error C2248: 
'boost::unique_lock<Mutex>::operator =' : cannot access private member 
declared in class 'boost::unique_lock<Mutex>'
        with
        [
            Mutex=boost::mutex
        ]
        ..\boost/thread/lock_types.hpp(110) : see declaration of 
'boost::unique_lock<Mutex>::operator ='
        with
        [
            Mutex=boost::mutex
        ]

This is happening on release branch. Could this be fixed?
