On a "normal" SysV, ipcs does an nlist of "/unix" to find the addresses
of the internal lists.  On the UnixPC it has to nlist "/etc/lddrv/lipc"
to get these addresses.  It first does a system("/etc/lddrv/lddrv -q lipc")
to see if you have ipc installed.

I suggest "lddrv -d"ing all ipc drivers, renaming nipc* as lipc* and
"lddrv -a"ing the one now named lipc.
