I believe it should be possible to typedef CGFloat to float.

I'm not going to work on this. File a bug upstream if you like.

I emailed the developer, who said:

It's probably easiest to mark it 10.5 and higher. I saw a couple other errors in there that wouldn't be fixed just by switching to float.

So I added a pre-fetch block for darwin 8 in r89361 to error out early.
