Doesn't work, it still considers these warnings as errors: $ gcc-4.3 x.c -c -Wall -Werror -Wno-error=pointer-sign cc1: warnings being treated as errors x.c: In function bar: x.c:4: error: pointer targets in passing argument 1 of foo differ in signedness
$ gcc-4.3 x.c -c -Wpointer-sign -Werror -Wno-error=pointer-sign cc1: warnings being treated as errors x.c: In function bar: x.c:4: error: pointer targets in passing argument 1 of foo differ in signedness This of course works, but I don't see the warning anymore: $ gcc-4.3 x.c -c -Wall -Werror -Wno-pointer-sign $ echo $? 0 $ gcc-4.3 -v Using built-in specs.
