Thanks for working on this. It is missing uglification but besides that I only have one small nit
Yes there seems to be a bug in that code. I've put it in a block for GCC specific code. (This is not obvious due to the lack of indention of the section.)
Oh, it might be because Clang's concepts are incomplete and so the feature-test macro's value is too high for us? Anyway, if you update everything in one fell swoop, I think that'd be best :-)
LGTM apart for the nitpick. Let's settle on what we do about it and ship this.
