Nevertheless, both of them rely on the same code snippet for default
initialization of the client and server address lists.

See the definition of ifreq_size for your OS. This is in
src/libCom/osi/os/XXXX/osdSock.h. We have only two versions of ifreq_size
conforming to the two different versions of this particular API that we have
seen.

Version for newer systems (probably originating from NetBSD):

#define ifreq_size(pifreq) (pifreq->ifr_addr.sa_len +
sizeof(pifreq->ifr_name))

Version for older systems:

#define ifreq_size(pifreq) (sizeof(pifreq->ifr_name))

If that doesn't work one might also replace the complete implementation in
src/libCom/osi/os/default/osdNetIntf.c with something else, but that level
of effort hopefully isn't necessary for NetBSD as Darwin is already working
with the more complex version of ifreq_size.

The server's address list can be seen if one types "casr 100" into the IOC's
command line.
