Yup, doing 'make clean' between.
What's the best way of getting a more detailed/verbose benchmark output?
(What I mean is, is there an easy way?!)
I compiled the x86-mmx version and stopwatch timed some 24-bit stamps. I
was getting between 10-15 seconds, with some of them up at 35-45
seconds... But I'd like to see how many tests/second this is actually
giving me.
John.
