That error appears in emacs' bytecomp.el, in the function 
byte-compile-check-lambda-list.  There have been recent changes to that 
function, which appear some time before emacs 28. That error message is removed.

So I'm not clear if I have any choice but to migrate to a newer version of 
emacs?  Or is there some other way around this?  Is it possible to just upgrade 
the emacs lisp files?
