Umm, a partial cygcheck output, inline, is not particularly useful. You
attach it as you would attach anything else to your email -- the exact
procedure depends on your email client (I'd open the help and search for
"attach").

YOUCH!!! That would be the first thing I would change about your
installation. You are running with a 4(!)-year-old version of Cygwin.

Actually, I was mistaken -- there *is* only one official ksh
implementation in the current distribution. Others have been proposed,
but, for one reason or another, did not make it in.

You are not using pdksh.

I don't know where you got this ksh, but it wasn't from an official Cygwin
installation. Thus, I would recommend either finding out where your ksh
came from (and contacting that venue for support), or installing pdksh
(which is what I've been assuming you use, so the recipe below should
work).

Umm, ok, I forgot to do "export vname_" in the first line, but you must've
figured that out, since it worked for you...

This sounds like the output from bash, actually... I suspect your
/bin/ksh.exe is a copy of bash.exe, but your installation is too old for
me to try figuring out whether this is the case. Just upgrade.

As I said, the version of ksh you have in Cygwin is not pdksh. Switch to
pdksh, and the above solution will work.
