Hi,
here is another, cleaner, patch to the OS X 10.6.8 build problem. It adds a non-notification version of windowDidBecomeKey, which windowDidEnterFullScreen now calls. This mean that 1) all functions now use the same pattern (the notification version calls the non-notification version) and 2) there is no need for the locally defined symbol NSWindowDidEnterFullScreenNotification any more.
David (R), if you think this is a good way to solve this, would you like to commit this patch, or would you prefer me to do it?
