    The change was made in rev 1.25 of in.c:
 
 revision 1.25
 date: 1996/09/09 20:17:24;  author: wollman;  state: Exp;  lines: +2 -2
 branches:  1.25.4;
 Set subnetsarelocal to false.  In a classless world, the other case
 is almost never useful.  (This is only a quick hack; someone should
 go back and delete the entire subnetsarelocal==1 code path.)
 
    This is the same revision that went into FreeBSD 2.2, so the problem
 should not exist there.
