I'm currently writing one of my own. The code it produces is very very
suboptimal because I haven't written an optimiser for it yet, but I hope
the actual parsing and syntax-tree code is straightforward.

http://github.com/jeffwar/ucc

I did a course at uni on the parsing side of things, and just made the
rest up from there. It only produces static binaries at the moment,
which uses a library that comes with the compiler, rather than the
system's libc.

This is due to different calling conventions (since I've yet to get to
putting everything into registers, it treats a machine as a stack
machine more or less).

Floats aren't supported yet, structs can be parsed, but no code can be
generated, and function pointers aren't supported either. I have a type
parsing branch, and my local working copy is almost ready to merge, then
I'll have function pointer support.

Next on the list is structs, enums and floats, then it may be able to
compile itself.

Thanks,
Rob
