Thanks for the report.
I've just applied a couple of patches that should fix the issue... I didn't use HideMenuBar()/ShowMenuBar() because those were the only Carbon dependencies left, so I replaced them by [NSMenu setMenuBarVisible: BOOL]. Thanks to you I've discovered this is 10.2 only, so I reverted to the old Carbon method.

Other than hopefully fixing compiling under 10.1.x (let me know if there are still problems!), the current CVS snapshot features:

- reduced CPU usage: I've investigated in the issue and now apps consume ~0.5/1% of CPU when in windowed mode with no activity.

- now uses "gcc3" as default compiler

- some bugfixes (of which one is important)

So anyone who downloaded the CVS snapshot is really encouraged to do a cvs update to sync with what's currently there. Thanks!

To Feanor: I missed your last post, sorry; here's a reply:
fixdemo only works when you've successfully made and installed the lib.
demo.dat isn't included in the WIP versions to reduce zip size; you need to download it and place it in the demo/ directory.
