--- Comment #18 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Another way of ignoring the unused result, friendlier on the eyes than
ugly macros or horrible casts, and even *inviting* the programmer to
write an explanatory comment, goes like

if (foo()) {
  /* The return value of foo can be ignored here because X and Y.  */
}
