I once started building a cross-compiler suite for 2.11BSD.  I never
finished, but I got close enough to estimate how long a "make world"
would take: about 10 seconds on a 133 MHz Pentium.  That's partly
because of the smaller size of the 2.11BSD distribution, but mainly
because the compilers were much faster: they had to be.
