Sure that should be useful for M-.

If you want to work on this: our fspec-pathname already looks at the
sys::file property. I guess it needs some modifications for CVS CLISP.
fspec-location should also make a location with a :line value (like
compiler-note-location does).

[A problem with "foo.fas" is that the fasl file and the source file
are not necessarily in the same directory or may have completely
unrelated filenames.]

Also look at frame-source-location-for-emacs.  If you find a way to
get the function name for the frame, then you could look up the source
file.  Doesn't work for lambdas or methods, but it would be better
than nothing.

I have no CLISP here, so I will not look at this issue.

Helmut.
