tcc is interesting. The code generation is pretty simplistic (read: trivially horrible for most things), but it sure is fast and small. And judging by the changelog, Fabrice is trying to compile the kernel with it.
For a lot of problems, small-and-fast is good. Hell, some of the things I'd personally find interesting don't have any code generation part at all (static analysis of annotated source-code - stanford checker on the cheap). And development doesn't always need good code generation (right now some people use "gcc -O0" for that, because anything else hurts too much. Now, the code from tcc will probably look more like "-O-1", but at least you can test out things _quickly_).
