They basically never cleaned up after bootstrapping themselves from OSF/1. The #ifndef alpha code is not compiled because it will never be referred to on the alpha.. The osf1 compat code is a much better match for the linux networking syscalls, so that's what's used. On alpha, the linux compat module depends on the osf1 compat module.. Naively, I'm uncertain why you're having compilation problems on alpha, since the code is just ifdef'ed out there anyway ;) Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
