I do not want to get this discussion off-topic.

I do not believe there is an "official" port of zlib to OS/400, but I do
recall seeing posts on other mailing list from people that have compiled
it. So in the worst case, we could likely port it ourselves and include
it in our binary distribution for OS/400.

After doing some digging around, I did find that IBM does include it in a
library that is included with their Apache server. I think they use it
for mod_deflate. I looked at the library and it is only exporting these
functions:

deflateInit2_
deflate
deflateEnd
crc32
inflateInit2_
inflate
inflateEnd

I looked at your patch and it doesn't look like you are using these. I
saw a "compress".

Could you possibly send me a list of the zlib functions you would likely
use? We had some of these same issues with the APR libraries and in the
past IBM has been cooperative in exposing these functions to us in their
library and then making an updated version available as a fix. Otherwise,
they only expose the functions they are using in the Apache server. This
process can take a while so it helps to be proactive.

Thanks

Mark
