To be clear, I was thinking that non-empty %destructor code that doesn't
contain $$ would not trigger the warnings. For example, the user may want
to use %destructor just for messages to the user:
%destructor {
fprintf (stderr, "Warning: statement at line %d was discarded.\n",
@$.first_line);
} stmt
This scenario has nothing to do with the default or per-type %destructor.
