Thanks, Brooks, I'll have a look at this.

In our FreeBSD derivative I made some changes to the kernel/t_sysv.c test
(I'm not sure where it lives in the NetBSD tree).  I've included them
below.

The changes are:
- Don't use the example msg struct name (FreeBSD erroneously defines it).
- Fix a broken call to open(2) with O_CREAT and no permission argument.
- ANSIfy function definitions.
- Improve failure messages.

-- Brooks

P.S. FreeBSD also erroneously defines union semun, but I'm working to
fix that so haven't included the change.
