Milestone:  To Be Determined  |  Component:  log
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 In Boost 1.61 Beta 1, a new error means to much forward declaration of
 basic_string_ref.

 boost/log/utility/formatting_ostream.hpp:39:76: error: redefinition of
 default argument for 'class traits'
  template<typename charT, typename traits = std::char_traits<charT> >
 class basic_string_ref;

 Its also declared in
 boost/utility/string_ref_fwd.hpp
 and
 boost/utility/string_ref.hpp


 Removing the fwd declaration in formatting_ostream.hpp:39 and all is
 working.

 Boost 1.61.0 beta
 gcc 5.3.0 (x86_64-win32-seh-rev0, Built by MinGW-W64 project)
