Apple's headers suffer from these 64 to 32 conversions as you have
noticed.  I don't understand why gcc complains because by default it is
not supposed to give warnings from system headers.  I suspect it is
related to templates and inlining.  We have been filing bugs with Apple,
hopefully the headers will be fixed in the next Xcode.  Until then, we
have simply hacked our headers with casts.  Over the last few days we
have been doing this on our dashboard machines, but there are a few more
to do.  Would you like a patch file to apply to your own Macs?
