// Apple SDKs don't define ::timespec_get unconditionally in C++ mode. This

// we're detecting this here instead of in <__config> because we can't include
// system headers from <__config>, since it leads to circular module dependencies.
// This is also meant to be a very temporary workaround until the SDKs are fixed.
