One problem is that, as far as I know, common lisp doesn't have
`eval-and-compile', and my code is meant to work with both elisp
and common lisp.  In any case, as I wrote to Michael, I plan now
to use defsetf only at top level.  So thanks for the suggestion,
and do feel free to keep this bug closed as "wontfix".
