I don't remember.

I renamed away the compare-w.* files I had copied into /emacs-24.3.
Then, as before, compare-windows did not work: it gave the error
message "Cannot open load file: compare-w".

I then brought up emacs -Q from Cygwin.  There, compare-windows
worked.

I then added /emacs-24.3/lisp/vc to my load path in .emacs.
Thereupon, compare-windows worked in my own Emacs.

It appears that something I did, in my .emacs file or elsewhere,
caused my Emacs not to load lisp/vc.

I have had similar problems with previous versions of Emacs --
libraries that were there, but were not being looked at -- and solved
them the same way, by putting them explicitly in the load path.  This
time, it did not occur to me to do a thoro search for the missing
compare-w.*; I supposed it had been left out instead of tucked away.

It seems not to have been a bug, but one way or another, the thing is
working now.  Thank you for your efforts and your patience.
