     Additional data points:
     1) Under Emacs, vm (mail reader viewmail) compiled for Emacs 25.3 
does not work for 26.1.
     2) Attempts to compile vm-8.2.0b under Emacs 26.1 fail due to 
changes in how Emacs
          processes Lisp.  This is a registered bug, at 
"https://bugs.launchpad.net/vm/+bug/1763377".
          There is a patch, which at least in my case fixes one problem 
but reveals another.  (Build log
          available on request.)


                     Respectfully,
