>Description:
Under ksh the following conditional test fails:

   $ test "-n" = "-n" -o "-e" = "-e" && echo ok
   ksh: test: -n: unexpected operator/operand

This fails if a '-a' is used instead of the '-o' as well.
Using '==' instead of '=' also fails. Use of strings other than
'-n' (or something that may be recognised) works:

   $ test "-hjhj" = "-hjhj" -o "-yuyu" = "-yuyu" && echo ok
   ok

The first test works fine under bash.
>How-To-Repeat:
1) Type in:
     /bin/ksh
2) Type in:
     test "-n" = "-n" -o "-e" = "-e" && echo ok
