Yes, on BSD, sa_family_t is an unsigned char. > But it's the same in our pfinet server, so the trunctation happens > there, I just checked.

It's coming from ./sysdeps/mach/hurd/bits/socket.h which uses __SOCKADDR_COMMON from sysdeps/unix/bsd/bits/sockaddr.h So we're basically screwed: sa_family can't have values beyond 255. That's the issue with using Linuxish values in pfinet while GNU/Hurd usually uses BSD interfaces... Samuel -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
