Dumpling emacs with diary/calendar bug?

[Leon]

Hi there,

I just knew this nice feature of emacs. Trying to dump emacs with a
very simple symfile that has one line:

(load-library "diary-lib")

After this, the executable runs OK except it can't mark dates in the
calendar properly. Take a look at the attachment. You can see each
marked date is displayed with a normal face and a [=+-] alongside.

Any fix?
