I have this definition using NSUInteger
-(id)initWithXExtent:(NSUInteger)xExtent yExtent:(NSUInteger)yExtent;
and I was stupidly calling it like this
GameBoard *gb = [ [ GameBoard alloc ] initWithXExtent:5 yExtent:-10 ];
and I didn't get a warning and spent 5 minutes trying to figure out
why my yExtent was totally screwed up. I'm using -Wall, -Wextra -Winit-
self -Wundeclared-selector which normally complains about everything,
but not this. NSUInteger is just a typedef isn't it, so this is really
unsigned int / int and I was expecting a warning. Have I missed a
warning flag or is there some NSUInteger artifact I'm not aware of?
