Is this known or is it deduction? (In case there is any confusion here: I do understand very well how compilers can be implemented on naked machines without preexisting tools (and indeed I've done more-or-less this with assemblers on microcomputers, ending up with a perfectly fine assembler which used the wrong opcode names, because we didn't know what the right ones were...). So my question `how was x done' is not `I don't understand how you can do this' but `historically, what were the steps in this case'. What I'm trying to find out is what the actual course of events was for C, so I can give glib answers to people (:-)) --tim
