[Bug c/37186] New: -Wno-error=pointer-sign does not work

[edwintorok at gmail dot com]

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
