Yes, you are right on that, but that is only on linux, not on *BSD (where I tried it). I still don't know why is these, Can you try using gcc 3.0.2?
For the compiled version, please read both mops.c you will see there is no difference except for the definition of the array which if no missing something doesn't have anything to with the _benchmark_.
