The `#elif` that I'm changing is for that `#if`, so we'll fall through to it and include the Clang resource directory's `stdatomic.h` after my change. I verified that this did fix my actual issue, but I also came up with an alternative solution, so I don't need this patch anymore. I'm happy to abandon if we'd rather not take this change.
