Agree.  I will be busy the next few weeks, but after that I will look 
into it and start a discussion to resolve the differences.

In the meantime I have a question: when byte-compiling vhdl-mode.el with 
Emacs 29.1 a 'defvar-1' ends up in vhdl-mode.elc, which causes an error 
in older Emacs versions:

File mode specification error: (void-function defvar-1)

Someone reported the error for Emacs 28.2, but I can't reproduce.  I can 
reproduce on Emacs 15.1.  Is this a known problem?
