within functions, use this instead:
(void)verify_true(...)
Or this, to give a better error message where possible:

(void) verify_expr (sizeof(*(atomic)) == sizeof(int), "wrong size");
...
The cast to void is unfortunately necessary to avoid a -Wall of
'statement with no effect'.
Likewise true of verify_expr().
