> Well, originally, the point was to clarify that these volatile stores end up without atomic semantics, regardless of whether -volatile:ms has been specified. The original version of this patch (with an inline implementation in intrin.h, just using a normal volatile pointer) wouldn't pass this test, but would pass if I remove this option. But if you prefer, I can leave it out.

Makes sense.
