".gz" is non-POSIX. z/OS UNIX doesn't supply a gzip or zip.  And Single UNIX
much prefers "pax" over "tar" nowadays.

I suspect WinZip is tar-savvy.  But is WinZip in base Windows?
(Cygwin rules!)

Again, non-POSIX, but distributed with (most) Linux.  Various zip
software may differ in treatment of symlinks and directory links.
Info-ZIP for example, expands links unless an option is supplied.
