It goes without saying that something that appeared in PWB was usually proprietary, while stuff that made it into 4.4BSD-Lite2 and/or NetBSD was almost certainly free software. The distinction of BSD vs. PD doesn't matter enough to encumber HISTORY with it. > -and again for > -.Nx 1.1 . > +and largely again for > +.Nx 1.0 . While both are true, i don't think it is important enough to mention the earlier one of these two rewrites in OpenBSD given that it lived less than a year before being superseded again. > .Sh AUTHORS > .An -nosplit > -The first free version was written by > +The public domain version was written by > .An Pace Willisson > in 1992.

OpenBSD uses Conklin's NetBSD 1.1 version (written in C in 1994). NetBSD uses jdolecek@'s NetBSD 1.6 version (written in yacc(1) in 2000). Neither uses Conklin's NetBSD 1.0 version (written in yacc(1) in 1993). http://cvsweb.netbsd.org/bsdweb.cgi/src/bin/expr/Attic/expr.c Yours, Ingo
