Does LINT matter?

I recall a C/C++ project at a major client-site over a decade ago, the tech team leader insisted on compiling with the highest warning level. This would ferret out inconsistencies and mitigate bugs. He really went wild when he deployed Gimpel Software's PC-Lint for C/C++ and peer-review sessions were brutal. 'Lint' was a seperate tool in the old UNIX boxes that checked for language-only anamolies or hinted at it.

Development now with .NET has an added dimension to the language itself - the underlying FCL and is all under the umbrella of 'Refactoring'. XTreme-Simplicity, DotNetRefactoring and FxCop are a few examples. FxCop is free and very extensible by incorporating 'rules' within the tool itself.
