Subject: nntpd on Sun4 running SunOS 4.0.1 drops core in getifconf()

For the first time for myself, I had to install news with NNTP on a
Sun4 running SunOS 4.0.1.  I installed news with NNTP on a Sun3/280
running 4.0.1 about a month ago, and it installed and is running just
fine.  However, apparent hardware peculiarities (byte alignment
restrictions, or perhaps a compiler bug) bit me on the Sun4.  It was
necessary to apply this diff to nntp-1.5/server/subnet.c in order to
keep the beastie from dropping a core (8.5Mbytes?!?) when executed.

Surely I'm not the first one ever to install nntpd on a Sun4 - did I
miss a patch somewhere along the way?
