--- Comment #28 from Adam Borowski <kilobyte at angband dot pl> ---
Please tell me: what would be other likely uses for such an explicit (void)
cast _other_ than trying to silence this warning?  I can't think of any.

Thus, I'd recommend to keep it simple and instead of adding complex
really_strict_unavoidable_warn_unused_result options, just make (void) shut it
down.  It did the thing for many years before.

There's too many system headers which abuse this attribute.  On one hand you
have realloc(), on the other write(STDERR, "error message").
