Right.  And that is one of the reasons why we have not addressed this problem.

We had originally planned to include Martin's fixes for dynamic thunks in
the next major gcc release, along with all the other changes which are going
to break compatibility.

However, the impression I've got is that thunks are on their way out as
part of the ia64 C++ ABI standardization.  If that is indeed the case then
we need to think very seriously about whether or not we want to use similar
standards for ia32 and other ports.  Which in turn means we may not want to
invest into fixing dynamic thunks at this time.  Particularly since they are
an ABI change.
