This part brought back memories from an even older time:
"Worst, it required two more programs: Flex and Bison."
In the early 80s I had the idea to port a C compiler to a new machine (I forget if this was K&R or pcc, but those were the only two C compilers you could get the source for at the time, legal issues aside...). At some point I had that same realization: uhh...this thing needs two other pretty big things: yacc and lex. The "first catch your fish" of compilers: "first port the parser-generators".
