That's the rationale for XEmacs's `declare-fboundp', which is intended
to support the preferences of external maintainers, and to some extent
features missing from 21.4.  But I thought there aren't supposed to be
external Lisp packages that can be used to build Emacs, they're all
included.  If such a situation is necessary, it's considered not a
good thing (add the needed library to Emacs or refactor to put the
needed function in the "right" library), and a warning *should* be
generated until the developers fix the problem.
