+This patch inserts if_nametoindex calls in each of the internal ISC
+routines that lookup the interface attributes. Neither getifaddrs or
+the existing ioctl calls lookup the index for the interface.
+
+This has been submitted as a patch for NTP bug 1960, and it can be
+removed when NTP is upgraded to version that includes a fix for 
+1960.
