Probably. What did you find of genuine errors? The problem with aggressive 
warning generation is the number of false positives in mature code.

On a related note, GCC has improved its warning generation a lot during the 
recent years. It still lacks laser-precision warning suppression, but it is a 
vast improvement over, say, version 2.95.3, which I am forced to use on a 
daily basis. The HP compiler ACC B.06.x series isn't bad either. It is 
starting to show value tracking, but so far it has not found a genuine error 
(yet). ACCs warning suppression is essentially non-existant.
