/etc/inetd is sensitive to ordering of lines in /etc/inetd.conf

[Tim Roper]

I think the attached diff of the 4.3bsd and 4.3bsd-tahoe inetd.c may be of
interest.  The se_bi flag in the data structure that holds /etc/inetd.conf
was not being reset when a non-internal entry was encountered after an
internal entry.  Hence the problem described in
<8903061946.AA20555 at emoryu1.cc.emory.edu>

I have no idea how SunOS versions relates to these.  We encountered the
problem with a System V implementation derived from bsd (for which a fix
was issued by the TCP supplier well before tahoe was announced).
