> If `/usr/bin/clang` can do it, why can't the open source binaries do it?
The main difference is that when you invoke Apple Clang (e.g.
`/usr/bin/clang`), you're actually going through a shim that calls `xcrun
/path/to/actual/clang/inside/Xcode.app`, and that sets the SDK to use by
default. For the open-source Clang, you might or might not even have a SDK
available, cause it's possible to install LLVM Clang without having any Xcode.
Regardless, I went ahead and tried implementing it in Clang:
https://reviews.llvm.org/D109460. This patch does solve your problem but it
creates other problems as well. I opened that review to see whether this was
worth pursuing or not.
Reopening until we get to the bottom of this.
