May I ask you where you got this information from? I was grep-ing around in the kernel source tree but I couldn't figure out that this old.lstat is syscall #40, let alone that it was a Xenix syscall.

Runs fine under the Linuxulator :) Are you telling me that the IBCS emulator is not really working? Unfortunately I can't ask for a Linux version. Have you ever had a look at the NetBSD one? Is it usable? Thanks for your help. -- walter pelissero http://www.pelissero.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
