(This was already reverted a couple of days ago.)

Do you have a timeline for how long it would take to fix the MacOS SDK? Is this something we could realistically aim to do in Clang 11 instead? I would really prefer for us to not have different defaults for Darwin versus everywhere else, so if waiting one release cycle is enough, that seems fine.

I'll split out the new flag at least and re-land for Clang 10, while we figure out how to set the default.
