FOSS Tools for C programming you cannot live without?

[phrasz]

I was wondering what tools everyone uses for C that are FOSS and you could NEVER imagine coding without.

Example: GCC (gcc and gdb), Valgrind, nano (eewwww ... yes I said nano), git.

Thanks and I'll take my answer offline ;)

already cited but valgrind, gcc, gdb, git, tig, vim. (rlwrap, not only for C dev, just all terminal thingy)

What's wrong with nano?

[phrasz → rkwz]

vi and/or vim elitists... I've always have used nano, but it seems that's not good enough for CentOS/RHEL guys.
