meant, and does the right think anyway, even though the code is wrong.
If you want a better answer, you should be able to grab gcc from the
apple cvs server and grep relax | grep -i 'apple local' and get hits on
all the relevant code. Roughly, think about field offsets and
Oh course, I could have it totally wrong, I didn't write the code!
