Some compilers I've written are Northwest C, Datalight C, Zortech C, Zortech C++, Symantec C++, Digital Mars C++, and the Digital Mars D compiler. The last one, DMD, still has code in it from those previous compilers :-/
I've also written a Java compiler (not from scratch) and a Javascript compiler/interpreter, and designed the ABEL (Advanced Boolean Expression Language) PLD compiler.
