I am not sure how that would happen--would you please give one example?

    Many of those warnings are bogus.

Perhaps the ones that remain are bogus, but that's because I fixed
many real ones that used to occur.

      One of the most common case of "bogus"
    is when a CL function is used in a macro and this macro is only used inside
    the file, so it's only used during byte-compilation and never at runtime.

I think the right fix for that is with-no-warnings.
However, it could be that the code that generates this warning
can be improved.
