Like I wrote in Trac, I think "CGGetActiveDisplayList" is not available for iOS
- the Apple reference makes me believe that. Thus, this has worked on my Mac but
I could not yet really test it on the iPhone. This is why I had choosen a
function available on almost any SDK version and OS, although unused in the code.

Also, do you really mean to check for "CoreGraphics.h" in case of lib

You might have noticed that I (finally) reworked my local FATE framework and it
seems to be much more stable and reliable than before (sorry for the everlasting
delay on that part) - except for the iPhone which I will try to fix asap and
test this patch better. I will also try to test the audio part in the second
patch then.

I will just need some time...
