Re: Problem with NSFont, NSSet combination

[Adam Fedor]

I was looking at this an narrowed it down further. If you include
objc/objc-api.h, you get the error. I don't know if it's really
important, but perhaps we shouldn't include this file in a public header
(it's in NSObjCRuntime now). I don't know why it's causing a problem,
but in general, objc-api exposes a whole lot of runtime internals that
most people don't need to be messing with.
