Thank you for the link, it's a useful one and the wording is better than
mine.

That's certainly true in branches <= 15, but in master, to my surprise,
I don't see any numerical comparisons of _MSC_VER since the recent
6203583b7.

I'm not sure explicit !defined(_MSC_VER) is all that more clear
than !_MSC_VER in the commentary. After all, we would probably
never (?) see an actual
#if (!_MSC_VER)
in a real code.

So I have mixed feelings on forcing define() on _MSC_VER, but if you
insist, I don't mind much either way.

What about other changes? Are there any obviously wrong or missed ones?
