Not for me. I tested this script on two machines, one with XP, one with Windows 7. On both machines I tried with Cygwin 1.7.7 as well as with the latest developer snapshot, to no avail. I even tried two different tcsh versions, the one from the distro and the latest from CVS. Your script works fine for me.
