zlib and libpng started life in /cygwin/latest.  The tarballs were
eventually relocated to /cygwin/contrib.  Since the setup.ini file is
autogenerated by a script on the sourceware ftp server, it should only
refer to the new location.

However, many mirrors never remove old stuff, even when the primary site
removes them.  So, some mirrors have BOTH /cygwin/latest/zlib and
/cygwin/contrib/zlib.  (Your local setup might be considered a faulty
"mirror" like this if you haven't pruned it in the last 9 months)

Now, if you run setup.exe from a local archive (that doesn't have the
official setup.ini from the sourceware ftp server) then setup.exe will
*create* a setup.ini that reflects your local archive.  But, your
archive has /latest/zlib and /contrib/zlib.  Presto: messed up
setup.ini.  Even when you "update it when it needs to".

(Note: this will also affect ncurses, which just moved from /contrib
into /latest about two months ago).

Basically, I think the mirrors need to be cleaned up -- mirror admins
should configure their mirroring software to remove stuff that has been
removed from their primary source.  But that's hard to enforce.
