No, this isn't the problem here. The real issue is that 
NSTextViewDelegate is not defined as a real protocol. It is just an 
informal protocol on NSObject. What we need to do is similar to this 
code from NSControl:

@protocol NSControlTextEditingDelegate <NSObject>
#ifdef __OBJC2__
@optional
#else
@end
@interface NSObject (NSControlTextEditingDelegate)
#endif

We need to make NSTextViewDelegate a proper protocol and make sure it 
still works with older compilers. I am willing to include such a change 
after the next release of gui. Please remind me if I forget about it.
