 well, I found the change they did, here
 http://git.videolan.org/?p=ffmpeg.git;a=commit;h=0bc5d4fd8bbb63be172978e888834a88a1e64fb0

 got trunk and altered the file but when I tried to compile it failed
 at some other place, it did compile FFmpeg ok tho, so would anyone be
 willing to try it for me?

does the below look right, i did git diff to create the below?
