calendar problem after upgrading

[Thomas L Roche]

I just upgraded my Cygwin emacs to

GNU Emacs 21.2.1 (i686-pc-cygwin, X toolkit) of 2003-01-23
on DRACO

and ran 'emacs --debug-init &'. Pretty much everything
loads OK (I
have a too-big .emacs and .desktop), except, at the
end, calendar
chokes:

How to fix or debug? (Please CC me as well as the
list, if possible:
I'm on the digest.)
