The keyword here is "warning". The code is compiled, however.

The LRM reference here basically says that the compiler implementor is
free to place whatever restrictions they want on pragma INTERFACE.

By the way, the types it is complaining about ARE scalar or access types.
They are "in" parameters. They also are private types. I have no idea
why VADS gives you the message. Ask them.
