In practice people don't sprintf const ints and the itoa above is nearly as optimized as it gets. It would be nice to see whatever counterexample you have in mind, with compiler version and settings.
If you do it as an answer with compiler version and settings, I will upvote it as useful. It would be good to provide a way to get the output length back. I've done that here: stackoverflow.
