If ksh compatibility is your main aim, the recommended way is to put

  [[ -n $ZSH_VERSION ]] && emulate ksh

at the top and write it in standard ksh.  This is supposed to remove all
your problems.  If it still doesn't work, then we want to know about it.
This sets all sorts of options you probably don't even want to know
about if you just want ksh compatibility.  (By the way, I think you had
option setting wrong back there somewhere:  it's `set -o OPTION' or
`setopt OPTION', not `export OPTION', which is why some of your attempts
didn't work.)
