Hello, Stefan.

First of all, sorry for being so strident in my opening post.  I now
understand what's happening.

No "threatening" warning message.  The message I got from that warning
message was that it would be necessary to replace easy-menu-add by some
other working code, which the message didn't specify.

OK, I got confused.  I might not be the only one.

I think I might be right about that point.

Yes.  I'd missed out the -B1 flag in my grep call.  :-(

Maybe it could say something like "which was always a no-op in Emacs",
thus reassuring maintainers that they needn't worry about lost menu
functionality.
