If your boss is still programming, even he probably looks at his 'old' code and cringes a little bit. I had a very similar experience recently. While the company couldn't afford a complete re-write of that piece of code (not mission critical) he DID see the value in going through and making it run under strict and -w.

If the code IS mission critical, selling a re-write of the code to OO shouldn't be a problem. If there is any chance that this code will be used going forward, or if it has functions that might be used by other callers, this would be a good time to make those functions cleanly available to other callers.
