Damn, unless you use "-i" when running postmaster, "-h" fails (telling you you're not running "-i", of course!).
We don't want to force folks to run "-i" all the time, as accepting outside connections raises security issues folks don't want to deal with unless absolutely necessary.
I'll look into having this routine use "-h" when appropriate under Linux/Unix, and add the code to do it always under windows - soon.
