one thing that I do not like about your patch is the modification of
"gfc_find_derived_vtab": You create two versions of it, one of which
creates the vtab if it does not exist, while the other version does
not do this. In short: I think this is not needed (it was removed in
my version of the FINAL patch). Or can you explain to me why this
would be necessary?

[Moreover, the problem is that your new "gfc_find_derived_vtab"
behaves different from the old one but has the same name, while your
new "gfc_get_derived_vtab" behaves like the old
"gfc_find_derived_vtab". Therefore, the places where you change the
behavior by keeping the call to "gfc_find_derived_vtab" are not
visible in the patch.]

Cheers,
Janus
