cool. that's three affirmations that bootstrap is not needed
to test frontend modifications. that equates to about 20 times as
many experiments I can make over the course my vacation. hopefully
I can fix a buglet and learn (a bit about) how this magic compiler
works, if not I can atleast slap together the beginnings of a
"Hacking gcc for dumm*es" guide :)

thanks.
