This code has always worked just fine for me before, and is based directly on benchmarking code I've seen and used before. The only thing I've changed is the code for doing the timing, which is correct as far as I can tell. It runs fine on UNIX boxes, but I changed the timing code since I didn't think djgpp supports the UNIX style timing calls. Unless DJGPP is doing something wierd to the individual arithmetic operations (ie, doing optimizations despite being given the -O0 flag), I've nary a clue why it's not behaving properly. -- ----------------------------------------------------------------------------- Jeff Standish http://www.cs.indiana.edu/hyplan/jestandi.html jestandi AT cs DOT indiana DOT edu May your deeds with sword and axe jlstandish AT acm DOT org Equal those with sheep and yaks
