gcc (at least as of version 4.6.0) is kind enough to point these out to us, (when given -Wunused-but-set-variable explicitly or implicitly via -Wunused or -Wall). One of these cases was a legitimately unused variable. Two were simply variables (named ignored) we were assigning only to squelch a warning about unused function return values. I don't seem to be getting those warnings even without setting the ignored variable. And the gcc docs. say that the correct way to squelch that warning is with a cast to (void) anyway. |
