44 * stuff that *used* to be included by user.h, or is now needed. The
45 * expectation here is that the user program wants to mess with kernel
46 * structures. To be sure we get kernel structures we have to define
47 * _KERNEL_STRUCTURES. Otherwise we might get the user version.
48 *
49 * This is a really aweful hack. Fortunately nobody includes sys/user.h
50 * unless they really, really, really need kinfo_proc.
