I haven't looked closely, but this appears to be the C4 compiler (or an update to it), which has been around for a while and is worthy of attention in itself.

  The C4 compiler is certainly fascinating and worth studying but don't believe that swieros's C compiler is based on that judging by their code [1][2]. There are similarities of course but well they are compiling the same language after all using some similar standard techniques like recursive descent parser [3]. Anyways, C4 is also very cool and focused on minimalism. Swieros's compiler seems much more extensive and even includes #define as the other comment mentioned and va_args.

    Oh I completely missed the fact that they're both written by the same person.
