Comment (by Zenju):

 I have the same problem, but disabling the warning when including
 "thread.hpp" is not sufficient. ADL drags in this overload (and thereby
 the warning) on multiple occasions in my own code when using a member of
 namespace boost with the commma-operator, e.g. a boost::unique_future:

 {{{
     std::list<boost::unique_future<bool>> dirEx;
     [...]

     auto itDirname = dirnames.begin();
     for (auto it = dirEx.begin(); it != dirEx.end(); ++it, ++itDirname)
         [...]
 }}}
