Err, __dead2 is a macro. For gcc we define it to something useful, and for other compilers we just define it as nothing. The kernel code uses this for things like exit1(), etc. It's in <sys/cdecl.h>. Some other kernel functions that need it if they don't have it are kthread_exit() and sigexit(). -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
