Comment:

 Another possibility could be to define a public print function which is
 used by the operator<<

 +#   ifndef BOOST_NO_MEMBER_TEMPLATE_FRIENDS
          template<class charT, class traits>
          friend std::basic_ostream<charT, traits>&
 -        operator<<(std::basic_ostream<charT, traits>& os, const id& x)
 +        operator<<
 +#   else
 +        template<class charT, class traits>
 +        static std::basic_ostream<charT, traits>&
 +        print
 +#   endif
 +        (std::basic_ostream<charT, traits>& os, const id& x)

 +#   ifndef BOOST_NO_MEMBER_TEMPLATE_FRIENDS
 +    template<class charT, class traits>
 +    std::basic_ostream<charT, traits>&
 +    operator<<(std::basic_ostream<charT, traits>& os, const thread::id&
 x)
 +    {
 +        return thread::id::print(os, x);
 +    }
 +#   endif
