Sorry, I cannot resist. Those of us old enough to have used lots of
computers before Unix existed remember when all {linkers|loaders|link-editors}
worked this way. The correct terminology is not "Unix linkers" vs.
"Smart linkers" but "Dumb linkers" vs. "Standard linkers." ;->
[Eh? The PDP-6 loader in the late 1960s certainly did it the dumb way. And
wasn't the 1965-vintage OS/360 link editor pretty dumb, too?]
