Much of Apple's toolchain is licensed under the Apple Public Source License 
(now Version 2).

The FSF now considers the APSL to be a free software license with two major 
practical problems, reminiscent of the NPL:

        • It is not a true copyleft, because it allows linking with other files 
which may be entirely proprietary.
        • It is incompatible with the GPL.

Looks like the APSL qualifies as free, but it is not compatible with GPL.
