I've noticed that SunOS4.1.3 has include files sys/msg.h, sys/sem.h,
and sys/shm.h even though it is a BSD4.3 os. OSF/1 V1.3 has the include
file socket.h, even though it is a SysV os. Since Berkeley IPC and
SysV IPC are distinct methods and useful in their own ways, I was wondering
how universal it is for Unices to have both methods. i.e. would it be
wise for a piece of PD software to rely on a system to have one, the other,
or both?

SunOS 4.1.3 has both the BSD and SysV libraries....

Yes. There is a SysV option when you install 4.1.3. However, the SysV
IPC headers are not located in 5include/sys. They're in plain old
usr/include/sys. i.e. they're standard to 4.1.3 and not SysV options.
In addition, in ucb/include/sys you find the same exact ones as in
usr/include/sys. No links, just copies.
