Well, after this morning's sup, I tried to config my usual kernel, and 
got the following errors:

	files.mac68k:57: syntax error
	files.mac68k:67: redefinition of `sbc'
	files.mac68k:68: redefinition of `sbc'
	*** Stop.

Seems like files.mac68k got screwed up a bit:

#	$NetBSD: files.mac68k,v 1.43 1996/04/28 19:18:42 briggs Exp $

# mac68k-specific configuration info

(lots of stuff omitted until we get to line 57:)
