Sorry about that. I got confused - too late a night. I thought that all the Celeron options set the SSE2 flag but looking at it again, they don't. I have a memory of a compile for PIII/Celeron which kernel panicked with "processor doesn't support SSE2" but I cannot reproduce this. My apologies once again, -- [--Partly Cloudy in Rabat, 19°C/66°F. Wind: W strength 12. Humidity: 73%-] The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet.
