Nope, we not only need the time when gcc was unmerged (-u), but also when it was merged (-l). When there's little time difference between merge and unmerge we can assume, that portage auto-cleaned the old version of gcc. If you combine -u and -l you need to grep (to be exact sys-devel/gcc-[0-9], because of sys-devel/gcc-config and sys-devel/gcc-apple). Yeehaw cowboy :) :)
