This thread kind of went off on a tangent about whether forward references are a feature or a bug, and I didn't get an answer to my actual question about whether there's a compiler flag to disable the feature, i.e. make it an error to call a method before the point where it's defined.
If there isn't one, I think maintainers of open-source Cocoa project will probably just need to bite the bullet and require Xcode 4.3, because there's no practical way of detecting when you're making a change that will introduce a build error in 4.2 and earlier.
