The current problem regarding `delete-directory' is already an example for that (at least Emacs22 warns during compilation, which Xemacs 21.4 for some reason does not with our setup...). >> More controversially :-), I think =E7=9C=9F Gnus should also stop defini= ng >> compatibility functions like `gnus-mark-active-p', and instead just >> start maintaining a `gnus-compat.el' library that would define functions >> like `mark-active-p' for Emacsen that don't define them. > > Please don't.

I know it's tempting, but please don't do that; it *will* haunt you later. The only solution is to radically drop support for older (X)Emacs versions and live with it. Others can provide a compat package if they want to, but do not put it in Gnus itself. -David
