It seems that this is related to Apple having changed the definition of the thread state structure to become more UNIX conformant (the change is within #if DARWIN_UNIX03)

[gauchi@…]

This patch fixes the compilation for me, but it is probably not the right way to do this it should probably be conditional, so it does also work on darwin<9

[pguyot (Paul Guyot)]

Fixed in r33409.
