Bug#698092: exim4: Fails to send mails on hurd-i386 with ipv6 enabled

[Samuel Thibault]

Package: exim4
Version: 4.80-6
Severity: important
Tags: patch
User: debian-hurd at lists.debian.org
Usertags: hurd

Hello,

After enabling ipv6 on a hurd-i386 box, I couldn't send mails with exim4
any more:

LOG: PANIC DIE
  Unable to get IP address for lo interface: 1073741846 Invalid argument

Digging a bit, it seems it would actually also happen on Linux if it
didn't have SIOCGIFCONF_GIVES_ADDR . It happens that GNU/Hurd's
SIOCGIFCONF does give the address, so the attached patch sets
SIOCGIFCONF_GIVES_ADDR on GNU/Hurd too, which fixes the issue.
