[RM D.7] This restriction ensures that there is no call to any of the operations defined in package Ada.Interrupts (Is_Reserved, Is_Attached, Current_Handler, Attach_Handler, Exchange_Handler, Detach_Handler, and Reference).
The restriction No_Dynamic_Interrupts is recognized as a synonym for No_Dynamic_Attachment. This is retained for historical compatibility purposes (and a warning will be generated for its use if warnings on obsolescent features are activated).
