</div>I have a hard time finding a gcc option to enable these "returned value not<br>

On the whole, GCC does a good job of not whingeing when it isn't necessary; not all analysis programs have such good heuristics.<br clear="all">
<br>I seldom use 'lint' these days (as in, I'm not sure when I did last use it). I had to check whether it was available on MacOS X and to my not very big surprise, it is not, but it tends to be available on the classic versions of Unix derived from AT&T System V.<br>
