M-x shell: Debugger entered--Lisp error: (void-variable s)

["odoncaoa" <odoncoa@gmail.com>]

Greetings,

I'm running GNU Emacs v21.3.1 (i386-mingw-nt.5.1.2600) on Windoze XPro. I'm trying to track down a problem that I'm having while trying to configure it to use Cygwin Bash, and UWin Ksh. The *nix environments have been successfully installed and configured, and function correctly on XP. I've got a bunch of code to facilitate the execution of these shells within emacs, however after emacs successfully executes all of this configuration code, I get the following error after attempting to instanciate either shell (M-x shell):

	Debugger entered--Lisp error: (void-variable s)
	  execute-extended-command(nil)
	* call-interactively(execute-extended-command)

I'm aware of defshell I'm wondering if anyone might have experienced a similar failure, and what their fix was. The following is the output of the result of the execution of my emacs initialization code.
