New That's ANSI C?!? ... YES
I just tried it undef GNU C++, GNU C and Solaris C++. Duff's device works fine under all of them.

(NOTE: I had to change "register n" to "register int n" for it to work in C++).

                                 It's C++, what do you expect? -NT - (tuberculosis) - May 11, 2003, 05:43:45 PM EDT
                             I would only use that if it were properly commented. -NT - (static) - (12) - May 12, 2003, 08:43:53 AM EDT

                                                     Most ASM Languages have a SWAP instruction. -NT - (ChrisR) - (3) - May 13, 2003, 12:25:46 AM EDT
