I was wondering how you would get around this problem. I suppose
the important questions to ask are

*  Is this change integrated into your implementation of ASIS?

*  Is it likely that other compiler vendors will implement it
   (i presume you have talked to them about it)

*  When will gnat 3.12p be released ;-) (someone had to be first
   to ask!)

If we can get everyone to implement it, it would make the ugly hack
for CORBA (cleverly invented by John Volan if I remember correctly)
no longer necessary.
