Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have installed emacs on Windows XP. I have also installed the
UNIXutils, which
include "diff". I have then tried to compare two buffers. After entering
the
names of the two buffers, I receive the following message:

ediff-setup: Symbol's function definition is void:
ediff-setup-diff-regions

and the file comparison then quits. What should I do to make it work?

Thank you
-Angelo Borsotti
