First of all, we're talking about integer overflow, and T'Machine_Overflows isn't defined for integers. It's defined for floating-point and fixed-point types only. (Check the manual.) Second, the issue is that some people are saying that the integer-overflow check works for them, using GNAT, even when they don't use -gnato, and my point was that it's reasonable to suppose that this might be true for some platforms and not others; the question wasn't about how to write a program that switches logic depending on whether integer overflow is detected without programming overhead or not, or anything of that nature. -- Adam
