Cygwin isn't the only platform where ksh is pdksh. You can't change all
the platforms. If you want your scripts to be truly portable, you should
try to accomodate the idiosyncracies of each platform. As mentioned
above, it's rather easy to change the scripts so that they work on all
platforms (including Cygwin). You can also test whether your construct
works, and if it doesn't, have a bit of pdksh-specific code.
Basically (again, as others mentioned), Cygwin's main ksh will stay pdksh
unless someone (i.e., you) packages and offers to maintain the "real" ksh.
If you decide to do this[*], please review the packaging instructions at
<http://cygwin.com/setup.html>, and good luck. It might also help to
review the prior discussions on the issue (search the cygwin-apps archives
[*] You'll also need to coordinate with the pdksh maintainer (me)
regarding the naming of executables and symlink policies. Such
coordination usually happens on the cygwin-apps mailing list (which all
maintainers have to read). When you ITP the package, this will come up.
