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.

For C-programming, vim or gedit, and I'll write a Makefile if it gets bigger.

For C++ I really want an IDE, and for that I use Eclipse with the CDT tools, it has the most comprehensive code-completion of all opensource IDE's, but as a bad side the program is slow java shit. But still the best of all.
