Not a bad thing, since LINT is not supposed to be runnable.  It only
supposed to test all options at compile time.  I'll change MSGSSZ to 16.

Too much for an undocumented option.

The author doesn't seem to be active in FreeBSD.  According to ancient
history, the System V IPC code was written by Danny Boulet, chewed on a
bit by NetBSD, and ported to an ancient version of FreeBSD by Jeffrey
Hsu.  According to modern history, it was obtained frome NetBSD and
FreeBSD-1.1.5.
