This is a fixed version of the prior posting with this name.

"Change Set:		RelativeZipExtractFix-nk
Date:			16 December 2002
Author:			Ned Konz
Version:			3.4b

16 Dec:
This fixes a problem with re-opening a zip in an ArchiveViewer under
Windows (by opening zips read-only), as well as fixing extraction with
subdirectories under Windows.

13 Dec:
This ensures that zip extraction relative to a given directory works
properly, and should eliminate the infinite recursion noted on the Mac.

It lacks AcornFileDirectory>>relativeNameFor: ; this should be added if
necessary before adding to the update stream.
