For GNAT 3.03 or earlier, take a look at Ada.Command_Line.Environment.

   Hum, why doesn't GNAT  take advantage of implementation  permission
RM95-A.15(21) :

"(21)
    An alternative declaration is  allowed for package Command_Line if
different functionality  is appropriate   for the external   execution
environment."

   Of course the choosen solution promotes portability (visible non
uportable feature) and I agree with this point of view. But may be if
all vendors agree on the specification ...

   BTW, why such a feature wasn't added directly in Command_Line ?
