Hey its only gcc :-), nothing to worry about. I think that 0 is nice number: so why don't optimize everithing to down it. -O seems to minimize numbers not calculation time. Does anyone know the flag to turn that off. till To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
