How do I get ready for C++17?

I have a piece of code which requires C++14.  I want to use something 
from C++17 but I also want my code to work now.  So I have

#if C++14 being used
namespace std {
// implement C++ function
} // std

I've looked in the documentation for Boost.Config and can't find any 
hints there.

What is the best way to do this?
