J-P Rosen asks

<<We have been unable to use Pro*Ada (Oracle) with Gnat. Apparently,
Pro*Ada uses heavily unchecked_conversions between pointers and
adresses, and other doubtful features; has anyone succeded to use
Pro*Ada with Gnat ?>>

Note that if you have pointers to unconstrained arrays, which are normally
represented as double ("fat") pointers in GNAT, you can force an alternative
single ("thin") pointer representation with a size clause:

   for x'size use address'size;

and this may make your code more ready to do battle with doubtful features :-)
