Let me clarify Jesper's post:

All these elisp files eventually call a separate executable program
"diff.exe".  There is no such program included in Microsoft operating
systems (guess why we all prefer GNU/linux?  :-), and that is what your
error message ("no such file...") is about.

So you're going to have to install diff.exe yourself.  A good place to
download it from would be <http://www.cygwin.org/>  (If I remember the
URL correctly - if not, do a Web search for "cygwin").
