Well, having been the GNUstep maintainer for over 8 years I guess I've 
done a fair amount :-)

Well sure, they've practically defined the Objective-C standard. But 
that doesn't mean everything they do is right. They've written a lot of 
code and I can't imagine all of it is perfect or conforms to the latest 
accepted style.

I guess I'm not religiously against the patch, particularly since it's 
off by default. RMS, for instance, is against the -Wall option, as it 
encourages an overly strict form of programming style (my 
interpretation). I have the same type of opposition to Devang's patch, 
although his patch, in my opinion, encourages an overly sloppy 
programming style.
