No, I meant just like you want, but instead of `#ifdef _WIN32` use `#ifndef _MSC_VER`, and use `#include_next <armintr.h>` for when not working in MSVC mode, i.e. behave as if our header didn't exist at all.

So I agree that it's useful to have on this individual header as well, not only rely on this guard in the intrin.h.
