Hmm, I'm confused about the status of MSVC: Jan Rheinländer has proposed 
f725e59b specifically for Win64, but that's clearly a C++11 language 
feature. Is a compiler that came out in 2014 really recent? Visual 
Studio 2017 claims to be C++17, after all. I have no Windows machine.

And I just committed the second patch relying on C++11.  :-/
