--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think this is less important as it normally should trigger only with -Wall
-Wsystem-headers.
Anyway, one fix could be e.g.

But that would break
#include <openacc.h>
struct S { operator acc_device_t () { return acc_device_none; } };
int
foo ()
{
S s;
return acc_on_device (s);
}
Another option would be just disable the warning for this particular builtin
where the warning is reported.
