Numeric constants are int by default. Add LL directly after the number to make them long long. E.g.: long long x; x = 332478632478624LL; -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
