The issue is indeed the warning message, from which I got the impression
that menu functionality had been removed.  The message appeared to be
telling me not to bother about this apparent loss in functionality.

It's a strange thing indeed to suggest using `ignore' in source code,
except for certain specific reasons.  Suggesting total removal of
easy-menu-add, if there is a way of doing that, would be better.
