Cool (sorry about the hassle on the compiler specification, new goodness =
coming on that front)

20 hours! Wow! My 486DX33 with 32MB RAM was able to buildworld (granted =
FreeBSD 1.1) in about 16 or 17 hours (8 or 9 if I disabled a boatload of =
junk I never used).

Of course, that same box would almost not be able to run FreeBSD today, =
let alone do a buildworld with the big-bloated pig dogs of gcc and =
clang=85 :)
