Thanks, i was already scared that the inverse proportional relation between
version number and performance which was so nicely followed since 2.95
would stop.
Adding a test to the testsuit to ensure that mmx intrinsics dont use
mmx registers is well, just brilliant.
Iam already eagerly awaiting the testcase which will check that floating
point code doesnt use the FPU, i assume that will happen in gcc 5.0?

Anyway iam glad ffmpeg compiles fine under icc.
