Interesting. But I seem to remember libc++ was not an issue when I built 52.3 
on 10.13 2 years ago.

I read somewhere that the deprecation is relatively recent. I've just asked the 
xcode list on groups.io. I think the configure script should check which 
version of darwin is used and based on that require the use of libc++, or not.

There again, I did not have to do that 2 years ago.
