[PATCH] D83250: [clang] Enable errors for undefined TARGET_OS_ macros in Darwin driver

[Jeff Muizelaar via Phabricator via cfe-commits]

jrmuizel added a comment.

This seems to have broken compilation for me on 10.15.

The stdio.h from the 10.15 SDK there's the following usage:

  #if TARGET_OS_EMBEDDED
  #define __swift_unavailable_on(osx_msg, ios_msg) __swift_unavailable(ios_msg)
  #else
  #define __swift_unavailable_on(osx_msg, ios_msg) __swift_unavailable(osx_msg)
  #endif
