Sure. Just change the above to use "(void)" in place
of the call to ignore_value:
$ cat in.c
int f (void) __attribute__ ((__warn_unused_result__));
void g (void) { (void) f (); }
$ gcc -Werror -c in.c
cc1: warnings being treated as errors
in.c: In function 'g':
in.c:2: error: ignoring return value of 'f', declared with attribute
warn_unused_result
