There it is, all done, NetBSD 0.8!
While it still says 386 BSD all over the place, trust me, I’ve built it from the NetBSD 0.8 CVS (with lots of donations for missing parts from 386 BSD).
Anyone interested can download it from sourceforge.
And no I didn’t bother doing the f2c thing, so many files were lost to the great bitbucket this isn’t a 100% restoration but considering the state it was in a few days ago, this is as good as it gets.
