if this makes a difference, something in ipc/util.c is missing. When I
added the code above, I also made the ipc_parse_version only return
IPC_64, because we never had IPC_OLD. Older glibc made the call with
IPC_64 set, so we needed the wrapper in sys_parisc.c. I just looked
at the 2.4 version of ipc/util.c and it's still ok ...
