In general, should I set my compiler to treat warnings as errors?

Question

Does the short term annoyance of fixing warnings that you could get away with pay dividends in the long run? What kinds of runtime errors can typically be avoided by doing this?

Answer 1

My view is that warnings are there for a reason, ignore them at your peril. While a few really are being picky, for the most part they do so for good reason. I'd rather have them fixed and a nice clean compile.
