So far, everything is unaltered. However on win32
there is a problem that two neccessary functions
are missing from the dll export. Therefore I
submitted this problem, but didn't receive an
answer yet. Yesterday I registered to be a
zlib developer, so I could contribute this
change (however small) to zlib.

I don't know, but I'll take that up with Mark
Adler and check in the necessary changes.
Below the mail I received from him and my answer.

I'm interested in this because tkImg could
in time use the same zlib1.dll that Tcl
is using. And if people download a new
zlib1.dll from zlib.net (1.2.4, with those
fixes, hopefully) they should not have to
wait for a new Tcl build to make use of it,
just replace the dll.
