There is a pull request to add new config macros for C++14 features 
(https://github.com/boostorg/config/pull/39), I have a few questions 
really, particularly for those more familiar with C++14 than me:

* Do we need these?
* Are these the correct names?
* Are the proposed tests correct?

Thanks, John.
