Actually, the man pages I've seen are not specific on this.  They all
say:

It's not immediately clear to me what "all but the last component of
pathname" means; presumably it means that the directory containing the
last filename in pathname must exist, but that the filename itself does
not have to exist.

I'd need to look at some sample implementations to see what that
actually means.
