I've two bugfix to add on zLibDll
(you can see discussion at http://forum.winimage.com/viewtopic.php?t=11 )

The better way is just copy files from
http://www.winimage.com/zLibDll/unzip101c.zip
And put them on contrib/minizip

Or just apply this latest patch

diff -c unzip101b/unzip.c unzip101c/unzip.c

All,

I just got back from vacation, and I plan to go through my backlog of email
and get a new version of zlib out.  There is a potential security bug in
zlib 1.2.1's inflate that needs to be fixed, and so I would like to get
1.2.2 out as soon as possible.
