But it is hard for people knowing C not that well but knowing pascal,
that's what I meant. Would you ever have be able to contribute to fpc if
the compiler had been written in C (yes, I did a prototype in C in '93
because I wanted a 32 Bit compiler to bootstrap :) )? Luckily enough I
got the money to buy BP7 so I could use at least PM to have enough
memory, this was before I got the idea to abuse TEMSStream to store
symbols :)

Yes, and then you can go drinking 3 cups of coffee ;) even using a
modern machine and not considering the unix centric approach it uses. If
you've bad luck, make distclean doesn't clean everything, happens
regularily, and you need to create a patch of your changes, re-unpack
the sources and apply your patch.
