And to give another one credit: I believe that the original Oberon system
(windowing OS, OO-variant of Modula-2-compiler...) was able to recompile
itself in the matter of a few seconds. (CPU NS32032 or similar).
Of course this is a minimalistic working environment, nedding only a few
100k in toto. (If I remember right, about 250k, including compiler,
editor and loader). BTW, one of the persons to credit is Niklaus Wirth,
and I've forgotten the name of the other one.
