xemacs-21.0-b57 build success on DUNIX 4.0D

I'm not on xemacs-beta, please include me on replies. Just to ensure that XEmacs is still working on DUNIX, I built xemacs-21.0-b57 on DUNIX 4.0D without any problems. The attached patch cleans up some warning messages that I noticed. What happened to advice, comint, and rsz-minibuf?
