From the logs that I could gather, this function was already there in 1992 (!) but it's not entirely clear that it was for AIX. But, right now, I'd have a hard time believing that it would be for any other kernel but AIX (the other ones I can see are (Linux, *BSDs). The oldest AIX we have now at AdaCore is 5.2. I'm wondering if Ulrich might have access to something a little older? -- Joel
