FWIW, for gdb as well as the above, the most recent round of modern
GNU runtime changes which neutered the Object class, have stopped
gdb's objective-c testsuite from compiling.   The gdb testsuite
probably needs to include its own root class now since there is
apparently no method to allocate an Object.  This would be needed to
test the above changes or could be done separately without the above
changes.
