     Type:  Bugs                       |     Status:  new
Milestone:  To Be Determined           |  Component:  conversion
  Version:  Boost 1.63.0               |   Severity:  Problem
 Keywords:  c++17, Visual Studio 2017  |
---------------------------------------+------------------------
 Some code, which uses boost::lexical_cast does not compile on Windows 10
 with Visual Studio 2017 Community using the compiler flag /std:c++latest
 (which enables c++17 standard). From what I understand from this page
 [http://en.cppreference.com/w/cpp/utility/functional/unary_function],
 std::unary_function will be removed with c++17. However, struct
 Trivial_converter_impl and struct rounding_converter in file converter.hpp
 derive from std::unary_function
