FYI: last week XEmacs in the CVS trunk (i.e. XEmacs 21.5-b28)
came to byte compile the default value section of defcustom
forms and report on undefined vars and functions found there.
For instance:

(defcustom foo (if (and (fboundp 'string-as-multibyte)
                        default-enable-multibyte-characters)
                   (string-as-multibyte "foo")
                 "foo")
  "doc string")

While compiling toplevel forms:
  ** reference to free variable default-enable-multibyte-characters
While compiling the end of the data:
  ** the function string-as-multibyte is not known to be defined.

(Emacs and XEmacs 21.4 don't do that.)
