I just noticed that sunCC in 12.6 supports the warn_unused_result attribute (yay!), but not suncc. It seems like an odd restriction; is it intentional?

Quick test case:

__attribute__((__warn_unused_result__))

int test_unused_result(void) {

  return 1729;

}

int main(int argc, char* argv[]) {

  (void) argc;

  (void) argv;

  test_unused_result();

  if (test_unused_result() != 1729)

    return EXIT_FAILURE;

  return EXIT_SUCCESS;

}
