--- Comment #2 from Reid Kleckner <rnk at google.com> ---
MSVC has warned on this since 19.15: https://gcc.godbolt.org/z/ToG3o4
https://docs.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-4-c4668?view=msvc-160
warning C4644: usage of the macro-based offsetof pattern in constant
expressions is non-standard; use offsetof defined in the C++ standard library
instead

Someone filed a similar issue with microsoft:
https://developercommunity.visualstudio.com/t/field-offset-macro-in-winnth-can-generate-c4644-an/331780

At this point, I don't think clang needs to implement an extension for this.
