Well, then that's another bug we should fix.

That's XCode complaining.  I'm not sure the underlying reason for it, but based on the reports, it looks like it's restricted to XCode 3.2 using gcc-4.2.  I've updated base to use gcc-4.0 in that situation, but I suspect there will be many other problems with such a configuration.
