Re: old-style backquotes warnings

[Richard Stallman]

    Check again the message carefully : it's complaining about the use of
    old-style backquote in cc-vars.el while compiling the cc-subword.el file.
    So it wouldn't be able to give any line-number info anyway.

I didn't understand that aspect of the problem.

How about this message instead:

   Loading `cc-vars.el': old-style backquotes detected.

That makes the relationships explicit
so that a person doesn't have to deduce them from the file names.
