Kevin - thanks for the advice, but still over my head. How precisely do I
set my PATH environment variable?
Is this done in the _emacs file? If so, what syntax do I use? (I tried
several, all wrong).
Is it done under Windows' System -> Advanced -> Environment Variables?
(Tried this too, also not working).

I'm close to giving up on using diff. If I can't get the PATH thing to work,
I'll download the UNIX tools as suggested above. If still no go, I give up.
But, wow, emacs can be frustrating! I do appreciate the help though.
