I have this definition using 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?
I have way more warnings than that enabled and I don't get a warning
either. I don't think there is one. File a bug.
-Wconversion will warn about this ("Also, warn if a negative integer
constant expression is implicitly converted to an unsigned type.")
But -Wconversion generates other undesirable and unavoidable warnings,
so you probably can't use it.
