The info-zip home page has a list of things unzip runs on, which effectively
gives a very comprehensive list of OS types:

the link to C-Kermit at the foot of the page reveals a large list of Unix

[The zip file "spec" is on infozip's pages:
the gzip file format is rfc1952 <>
the deflate compression method used by gzip is rfc1951
zip files can use a variety of compression methods - deflate is method 8.
As best I can tell only deflate and storing uncompressed (method 0) are
widely used nowadays.
In theory there's nothing stopping you putting a bzip2 stream (or whatever
arj or rar or any of the other archivers use) inside a zip archive if you
standardise on the compression method number.
Notice also the distinction - zip an archive format (put lots of files in
one file and take them out again) which allows entries to be compressed.
tar is just an archive format, gzip just a compression system.
how very unix - combine small tools to get a job done :-)
