How do you program?

Serious question: what kind of tools do you use for your C programming? I'm still not totally satisfied with tools that I've got, and I think that shell + vim + make is the best solution... Although I'd like to find out something more comfortable.

Awesome! This kind of thread is usually useless, but sometimes you get interesting answers: I've never heard about Valgrind, and it's good to know, even if I usually never make memory errors. Thanks /prog/
