[Dimitry Andric via Phabricator via cfe-commits]

dim added a comment.

Just encountered another similar error, apparently introduced in rGc8937b6cb9751807de1e69f0f0f70a9a58f8f5dc <https://reviews.llvm.org/rGc8937b6cb9751807de1e69f0f0f70a9a58f8f5dc> (as more additions to the `defineXLCompatMacros` function, by @lei):

To unblock my builds, I'm just going to use `-U` to undef these macros manually for now...
