9 Well, if the use of the mmxext flag leads to instructions in
10 the compiled code which the cpu does not have, then CRASH.

12 But the SSE instruction sets supersede MMX (and mmxext) and so the
13 mmxext flag is really unnecessary on Core i7 and many newer processors.
14 (Ffmpeg may have reasons for still using MMX but I don't know.)
