Until there is a machine description and an optimizer for these cpus written into gnu cc, there will be very little significant increase in performance.... Not that the orgs won't try to support them very soon, remembering that un*x supporters are trying to keep unix as the IP-working standard, the web standard, and all. Pentium MMXs don't often cause much performance increase in everyday operations, but their increase in blitting, etc. should be incredible. cheers, John ============== jddst19+@pitt.edu John Duncan Freshman, University of Pittsburgh "I'm not a doctor, but I ate one at the UPMC..."
