Fitting a respectable C compiler into a 512 *byte* binary!

I've written a lot of lisp, including a respectable number of macros, and I don't think I've ever been caught out by hygiene. I've definitely written broken macros that expanded to the wrong thing though.

What does the 80/20 rule look like in compiler optimisation? I suspect basic constant propagation and DCE gets you a respectable speedup.
