tcsh not working from within emacs 20-4

[Steve Kelem]

tcsh is not working from within emacs.
My .emacs file contains:
(setq explicit-shell-file-name "g:/Cygwin/contrib/bin/tcsh.exe")
;; For subprocesses invoked via the
shell (e.g., "shell -c command")
(setq shell-file-name "g:/Cygwin/contrib/bin/tcsh.exe")
(defun my-shell-mode-hook ()
  (interactive)
  (setq shell-completion-fignore
'("~" "#" "%" ".class"))
  (setq comint-completion-addsuffix
'("/" . " "))
  (setq completion-ignored-extensions
'(".o" ".elc" "~" ".bin" ".bak"
".obj" ".map" ".dvi" ".toc" ".log"
".aux" ".a" ".ln" ".lof" ".blg"
".bbl" ".glo" ".idx" ".lot" ".fmt"
".class"))
)
(setq shell-mode-hook nil)
(add-hook 'shell-mode-hook 'my-shell-mode-hook)
If I run M-x shell , the *shell*
window displays:
Process shell exited abnormally with
code 128
Any idea what this means or how to fix it?
Thanks,
Steve Kelem
