I have noticed the document. I don't know well about the .bat file on 
Windows，so I don't know how to configure it specifically to Clisp.

It does not affect my build using only SBCL. The only annoyed thing is 
the message that said the `maxima_longnames.exe` not found when invoking 
the maxima.bat. However, it dose not affect any thing else. I could 
comment the line...

Thanks a lot.

I just build Maxima using a Lisp-only build. I just use it on Windows 
platform. When I invoke maxima.bat, the warnings appear before the 
banner of Maxima. It does not affect the running of Maxima.
