It has been many moons since I got into compiling a compiler but here's how it basically works:
STAGE 1: Compile the new compiler with whatever broken crap compiler is already installed/hacked together/manually entered by punch cards/etc... STAGE 2: Compile the new compiler with whatever came out of stage 1. STAGE 3: As a sanity check, compile the new compiler a third time with whatever came out of stage 2 Because stage 1 should have produced a fully updated compiler, it's output (stage 2) should be identical to what that compiler in turn produced (Stage 3). This is where it's failing for me.
