shell problems after upgrading NTEmacs from 19.34 to 21.2

[swengtoo@my-deja.com (Swengtoo)]

Greetings,
I just bit the bullet and upgraded my NTEmacs from version 19.34 to
version 21.2.

The new (ver. 21.2) NTEmacs is wonderful, but for some reason the
shell command doesn't invoke cygwin's bash as it used to do for me
under ver. 19.34. Instead, it invokes Windows command shell (via
cmdproxy.exe, I'm using W2K). I follow the instructions in
http://www.gnu.org/software/emacs/windows/faq7.html#shell exactly, but
that doesn't seem to help.

Here is an execrpt from my .emacs file (that's been working perfectly
for the past 4 years and hasn't changed since then) relevant to the
subject:


	(progn ; not really win, just bash under win.
	  (setq shell-file-name "sh")
	  (setq explicit-shell-file-name shell-file-name)
	  (setq explicit-sh-args '("-login" "-i"))
	  (setq shell-command-switch "-c")
	  (setq archive-zip-use-pkzip nil)
	  (setenv "SHELL" shell-file-name)
	  (setq win32-quote-process-args t)
	  (setq win32-enable-italics t)
	  (setq comint-process-echoes nil)
	  (setq hexlify-command "//c/EMACS-21.2/bin/hexl -hex ")
	  (setq dehexlify-command "//c/EMACS-21.2/bin/hexl -de -hex ")
	  )


Has anyone encountered this problem before? Do you know about
something that has changed and is missing from the above code? I know
I can "play" with the SHELL registry entry for emacs, but the
documentation clearly says that if I want to avoid that I can use
(setq explicit-shell-file-name shell-file-name).

Many thanks in advance!
