I finally tracked down the bug causing ipc_perm, messages and semaphores 
not to work properly.  

In /usr/include/sys/ipc.h 
After 
#define	IPC_R	0400

#define IPC_M	10000	(decimal) should be 
               ^^ 
#define IPC_M	010000   (octal) 
                ^^
This caused (mode & IPC_M) to always return true and 
msg_perm.mode was never evaluated.

As changed, it works fine.
