Yes.
I had to introduce the following alias:

(defalias 'view-diary-entries 'diary-view-entries) ;which was even
obsolete in the diary-lib version of xemacs

But also 

(defalias 'general-holidays 'holiday-general-holidays)
(defalias 'oriental-holidays 'holiday oriental-holidays)
(defalias 'local-holidays 'holiday-local-holidays)
(defalias 'other-holidays  'holiday-other-holidays)
(defalias 'hebrew-holidays 'holiday-oriental-holidays)
(defalias 'christian-holidays 'holiday-christian-holidays)
(defalias 'islamic-holidays 'holiday-iclamic-holidays)

Because of the  the following ChangeLog entry

Frankly the rationale of renaming functions is beyond me, since it
breaks backwards compatibility.

He did not!

Right. I will try that. My favorite debugging tool is edebug. Is there
anything better around now you could recommend?
