The setkey code hasn't changed in months, so something else is wrong.  The
problem started yesterday when libc didn't compile -- so I tried a 'make
libraries' which finished okay, but then the setkey problem started.
(I think I picked the wrong moment to cvsup.)

Probably the libraries are not consistent with the rest of userland at this
point, I would guess.  Any ideas how to fix it?
