Which testsuite is this? I should note GCC uses dejagnu (and you can make your
own testsuite using that too for other compilers too) which allows you to do
things like:
```
#include <a2i/str2i.h>
int
main(void)
{
unsigned char n;
str2i(signed char, &n, "0"); /* { dg-error "-Werror=pointer-sign" } */
}
```
Which is easier to maintain than shell scripts like you provided in comment #4.
Note a simple dejagnu testsuite supports dg-error/dg-warning by default; GCC's
version of dg-error/dg-warning has more features though.
