gpointer in an any/BonoboArg

[Jacob Perkins <jap1 users sourceforge net>]

I want to put an opaque gpointer in a CORBA_any/BonoboArg, and have that
any be correctly returned from Bonobo_PropertyBag_getValue. What is the
correct typecode for the any? I've tried using TC_null and TC_void, and
while the any is returned, it's _value is always NULL (even though in
the PropertyBag, I do any->_value = opaque).
Thanks
