I know that, I was not expecting the patch to be accepted but maybe 
someone with more knowledge about ffmpeg can fix this.

You dont need to believe me. But this instruction IS specific to G5 
processor and is not supported by gcc-4.x on 32bit implementation.
The build fail on mac osx 10.4(default compiler is gcc 4.0), but 
whatever, its not like ppl use mac anyway.

hard code its bytes? How can this be useful, please develop your idea 
some more.
