-Wno-pointer-sign
Don't warn for pointer argument passing or assignment with different  
signedness. Only useful in the negative form since this warning is  
enabled by default. This option is only supported for C and Objective-C.
-Wsign-compare
Warn when a comparison between signed and unsigned values could  
produce an incorrect result when the signed value is converted to  
unsigned. This warning is also enabled by -Wextra; to get the other  
warnings of -Wextra without this warning, use -Wextra -Wno-sign-compare.

I can try them next time, as -Wno-pointer-sign or as -Wno-sign-compare.
