[kaffe] getifaddr for Linux 2.0.x (was: Patch queue status update)

[Kiyo Inaba]

Hi,

> kiyo's getifaddr.c patch: unresolved.
It is discussed recently, and my idea is to detect the existence of
/usr/include/netpacket/packet.h. I attached a patch based on this
idea but I am not sure whether there are some system which
1) does not have 'getifaddrs'
and
2) linux based and have netpacket/packet.h.

At least RedHat 8.0 has 'getifaddrs' itself, and Linux 2.0.x (sorry
I can not specify exact version, but it is debian) does not have
either 'getifaddrs' or 'netpacket/packet.h'. If there are some system
which exactly match the criteria I mentioned, this patch is effective.
