Ugh. I really shouldn't try writing code after two days of travel hell.
Try this one:
*** in_var.h.old Tue Nov 14 14:52:43 1995
--- in_var.h Wed Jan 3 07:02:45 1996
***************
*** 106,111 ****

IA_DSTSIN(ia):IA_SIN(ia))->sin_addr.s_addr != (addr).s_addr; \
ia = ia->ia_next) \
continue; \
+ if (ia == NULL) \
+ for (ia = in_ifaddr; \
+ ia != NULL; \
+ ia = ia->ia_next) \
+ if (ia->ia_ifp->if_flags & IFF_POINTOPOINT && \
+ IA_SIN(ia)->sin_addr.s_addr != (addr).s_addr) \

(ifp) = (ia == NULL) ? NULL : ia->ia_ifp; \
}
