Don't overlook the fact that lots of bug-finding tools support plain old C best. Yes yes, it needs them more, but... at least the tools exist!

Get all the tools. There are free tools like "sparse", a tool Linus wrote for his kernel. There are expensive tools like Coverity. Get them all. Use them all.

Build your code with all the warnings enabled. Use multiple compilers, even if they don't compile for your target.
