+// Detect warnings inside any header.
+// The build command above filters out warnings inside non-objc headers 
+// (which are noisy with -Weverything).
+// -Wno-undef suppresses warnings about `#if __cplusplus` and the like.
+// -Wno-old-style-cast is tough to avoid in mixed C/C++ code.
+// -Wno-nullability-extension disables a warning about non-portable
+//   _Nullable etc which we already handle correctly in objc-abi.h.
