I think that it works. I know that the "old way" works with -j values up to 20 (haven't tried anything higher). There were issues with -j for a while, but those have been fixed. They were inadvertantly introduced when we went to building modules. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
