Hi,

In emacs -Q, eval

  (require 'bytecomp) ; just for the defvar

Now 

   C-h v *compil*warn* TAB TAB

"byte-compile-warnings" should be among the matches, but that's not
the case.


Thanks,

Michael.

You were right on the money.  I installed a slightly refined fix, which
tries to optimize away a few cases.
Thank you,
