Thank you for the patch. Are you able to test it with a version of GNU Emacs older than 23.2? I see that you tested it with XEmacs 21, but as I recall there were quite substantial differences between XEmacs 21 and GNU Emacs of similar vintage. In addition, if you are able to do the archaeology to report *when bytecomp.el was added to Emacs*, i.e. how far back you have to go before `emacs -l bytecomp` will fail, that would be helpful. I'm betting it's well before the oldest version we care about, given that bytecomp.el (in 27.1) lists its oldest copyright year as 1985 and <j...@lucid.com> as the original author, but I'd still like to know for sure. zw
