This isn't quite right.  Whether a symbol is typed doesn't affect the 
warning as far as I can tell.  In case it helps, I believe we've only 
implemented the first level of warnings I describe here:

  http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00107.html

Moreover, types don't have destructors; symbols do.  I made the same 
mistake at one point in the above message.
