That's odd, because the person who did the binary test claimed it was just the 
change to this file that caused the breakage.  That is, if they reverted 
linux_ipc.c to the revision before the kern_semctl() changes it worked fine.  
Can you test that to see if that's true for you?  (You'll have to revert last 
revision of linux_util.h as well.)

Unfortunately I really can't see what is failing.  Perhaps if you could 
capture the output from starting acroread on a working system so we can see 
where the output starts to change that would help.
