Why are you using gzip to handle archives created by PKZIP? I
thought that PKZIP worked with ZIP archives, and that gzip's ZIP-archive
capabilities were quite limited.
There are programs which were designed to deal with ZIP archives, and
they have been used on z/OS:
http://www.info-zip.org/
I'm not a z/OS user, so I know nothing, but there is at least one in
the Info-ZIP group, so you may be able to get some help if you have
problems building or using the Info-ZIP Zip and UnZip programs on z/OS.

It's not my program, so I know nothing, but I would not bet that gzip
on any system type can do this. The Info-ZIP programs definitely _can_
handle large-file ZIP archives on Solaris (although a version number
would be an interesting datum when describing any OS). HP-UX, Tru64,
and VMS, too, for that matter.
