We have attempted to fix most comp warnings in [1].  However, there are
XEmacs compatible code that still causes some comp warnings, so using
this bug to track this.  The current list of warnings are as the
following:

,----
|  ■  Warning (comp): debian-changelog-mode.el:1694:12: Warning: the function ‘set-extent-property’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1691:25: Warning: the function ‘make-extent’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1669:18: Warning: the function ‘delete-extent’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1668:42: Warning: the function ‘extent-end-position’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1667:42: Warning: the function ‘extent-start-position’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1666:22: Warning: the function ‘extent-detached-p’ is not known to be defined.
|  ■  Warning (comp): debian-changelog-mode.el:1640:14: Warning: the function ‘set-keymap-name’ is not known to be defined.

Will re-evaluate if XEmacs compatibility would be dropped.

Does the package currently work (somehow?) with XEmacs? At least dh-elpa
byte compilation does not support XEmacs, but I have not tested the
binary package with XEmacs.

I don't know, but I guess we will find out once "someone" packages
XEmacs again ;) My hope was those legacy compatibility code will help a
little for the transition, which may turn out to be useless, but will
see.
