Would you accept a patch that eliminated this warning by disabling
-Wobjc-method-access? 

The problem is Objective-C classes usually are in two files, the 
header and the .m file. Cocoa.m places both the interface and
implementation of the QemuCocoaAppController in one file, 
so that is why I think we are seeing this message.
