So is it just me or does nobody care about warnings (ide, compiler, etc) in their code?

I do care and If I encounter warnings not introduced by me I enjoy telling everybody how to set up their environment to see warnings on every build.

Fore me there are four stages to handle warnings:
1) fix it
2) work around it
3) intentionally suppress it at this single point
4) intentionally suppress it through compiler settings

But never ignore it.

In C/C++ projects I sometimes use -Wall and -Wextra because sometimes you find errorneous code through warnings.
