Is IPV6_PKTINFO not usually undefined on GNU/Hurd?

[Hiroyuki Yamamoto <yama1066@gmail.com>]

Hello,

I tested the compilation of the avahi package (version 0.6.19-2).
The qt4-x11 and the libdaemon which were necessary as Build-Depends were
compiled as follows:

qt4-x11 (version 4.2.3-1):
The mesa-common-dev and libgl1-mesa-dev package were held in version
6.5.1-0.6,
the po-debconf was held in version 1.0.8, and the qt4-x11 was compiled.

libdaemon (version 0.10-1):
The libdaemon source was patched as described at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=407867 ,
and was compiled.


On the compilation of the avahi package, the undefined error occurred as
follows:

socket.c: In function 'avahi_send_dns_packet_ipv4':
socket.c:467: warning: unused parameter 'interface'
socket.c: In function 'avahi_send_dns_packet_ipv6':
socket.c:608: error: 'IPV6_PKTINFO' undeclared (first use in this function)

Is IPV6_PKTINFO not usually undefined like PATH_MAX on GNU/Hurd?
