Well there is more than one way to kill this cat.  Let me add my cocktail.

I have a need to automatically run scripts, totally written in cygwin 
using ksh as my shell.  For example I have a number of .bat files 
performing necessary startup functions:
        echo off
        set ENV="/dev/null"
        set PATH=C:\cygwin\bin;%PATH%
        SET IS_CYGWIN=true
        set HISTSIZE=1200
        set HOME="/dev/null"
        set CYGWIN=tty
        ksh -c "C:/cygwin/backup_e

The above "backup_e" is the work horse.  It can be anything from a 
complicated script or starting up anything to running under cygwin.

In this case I'm not providing any parameters that can be added if you 
so desire.  Basically backup_e is an ordinary cygwin script:
        #!/bin/ksh
        #
        #       backup_e
        #
        #       Perform a incremental backup of drive e: of all
        #       files having the archive attribute set.
        #
        #       get list of files ready to archive
        exec 2>/tmp/_backup_tracelog 1>&2
        echo -e "Started - `date`"
        set -x
        cd /e
        /c/WINDOWS/system32/cmd /c "dir /s/b/a:a *" >/tmp/_backupe_1
        if [ -s /tmp/_backupe_1 ]
        ....
        ....

Using this scheme does NOT require you to setup/configure cygwin's 
"cron".  You can use Window's "Scheduled Tasks" feature under "Control 
Panel".
