In the iForth config.fs file
\ $Date: 2009-05-20 13:27:22 $ $Revision: 1.5 $
it is replaced by

: nil<>?   ( addr -- false | addr true = If addr is nil, then return
           \ false, else return address with true )
    ?dup ; \ relies on inlining

It's unlikely I wrote that definition, it was probably done
by Dick (he did the port himself but asked for advice).

The last comment is probably no help, but that's what you get.
