I forgot to mention that I've made this header work for C++14 not just C++17. I did this for similar reasons as we make some C++17 things available for -std=gnu++11 and -std=gnu++14: #if __cplusplus > 201402L || !defined(__STRICT_ANSI__) // c++1z or gnu++11 But in this case <charconv> is a completely new header so we don't have to limit it to -std=gnu++NN modes only. The new functions won't pollute namespace std unless the new header gets included, which strictly-conforming C++14 code won't do anyway.
