Hi,
I'm cross compiling juce for osx on linux using clang 3.5.1.
I get this compiler warning, which seems correct to me, but I don't know objective c or osx programming very well:

It's far from from unlikely that my compilation options are wrong (they are based on the result of running "xcodebuild -verbose"), so I would also appreciate to know if this warning is completely wrong.
Thanks
