There are other tools than GCC for measuring the 'quality' of code - and
some of them get antsy (or, more accurately, used to get antsy) about not
using the values returned by a function, the obvious example being 'lint'.
On the whole, GCC does a good job of not whingeing when it isn't necessary;
not all analysis programs have such good heuristics.

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.
