I took a quick look.  The warning comes from this code in
mule-cmds.el, part of the function set-locale-environment:

	(when (get-language-info current-language-environment 'coding-priority)
	  (let ((codeset (locale-info 'codeset))
		(coding-system (car (coding-system-priority-list))))
	    (when codeset
	      (let ((cs (coding-system-aliases coding-system))
		    result)
		(while (and cs (not result))
		  (setq result
			(locale-charset-match-p (symbol-name (pop cs))
						(locale-info 'codeset))))
		(unless result
		  (message "Warning: Default coding system `%s' disagrees with
  system codeset `%s' for this locale." coding-system codeset))))))))

As far as I could see, `(locale-info 'codeset)' on Windows returns the
codepage that corresponds to the current language, e.g. cp1252 for a
Western-European locale.  But this codepage is not in the list
returned by coding-system-priority-list; thus the warning.

I don't really understand the rationale for this test and the warning;
Handa-san, could you please shed some light on it?  What does this
code try to find out, and what is the meaning of the warning?

TIA
