Steve,
that pretty much answers my question about it being a bug in machten. 
the problem arose initially on solaris (it was sent to me as a
question) and the machten port gives the same answer as the solaris
port. but if NT gives the expected answer then there is possibly
something wrong with gnat???  I will send it on to ACT

THANKS!  jim
