It's not that bad (or difficult), really. It's a hand-written parser for a subset of C that emits assembly code right away. This is how compilers like Turbo Pascal used to work (see http://www.pcengines.ch/tp3.htm for an explanation of what's happening).
Sure, you could apply cosmetic changes like making "*++e = bla;" into "emit(bla);" and you could move the cases into independent methods (that are used once), but this isn't meant to be a state-of-the art compiler and it won't become one if one applies best practices to it.
