--- Comment #2 from Hans Wennborg <hans at chromium.org> ---
Reid pointed out that this is the same old "MSVC makes all intrinsics available
all the time and the user has to do cpuid checks" problem.

In this instance, I think the fix will be to not use this intrinsic in ffmpeg.
See http://crbug.com/556735 for more info.

I'll close this bug for now.
