First of all, thanks for the quick response. At the very least this 
sheds some light onto the history and how this situation likely came to 
pass. I'll see if i can put together a patch during the next week or so 
that would bring our definitions regarding System V IPC in synch, i'll 
also try to see if i can find additional occurances of similar 
discrepancies so these could be fixed in a single run.

Any additional sugestions/objections are always greatly appreciated.
