Comment(by dtrebbien@…):

 I developed a partial work-around for those who, like me, are only
 interested in a "`basic_path_traits` template" for (`char`,
 `std::char_traits<char>`) and (`wchar_t`, `std::char_traits<wchar_t>`):
 {{{
 #!cpp
 namespace detail {

 template <typename char_t_, class traits_ = std::char_traits<char_t_> >
 struct boost_ticket_1936_workaround;

 template <>
 struct boost_ticket_1936_workaround<char>
 {
         typedef boost::filesystem::path_traits
 boost_filesystem_path_traits;
 };

 template <>
 struct boost_ticket_1936_workaround<wchar_t>
 {
         typedef boost::filesystem::wpath_traits
 boost_filesystem_path_traits;
 };

 } // end `namespace detail`
 }}}

 Using this code, the generic path traits type is `BOOST_DEDUCED_TYPENAME
 detail::boost_ticket_1936_workaround<char_t_,
 traits_>::boost_filesystem_path_traits`
