	When trying to compile ipsend for vax, it fails with

    compile  ipresend/sock.o

*** Failed target:  sock.o

	I discussed this with Jason, and he said that the problem
	isn't boolean_t as such (it's defined to int under _KERNEL in
	<sys/types.h>).

	However, Jason points out that the real problem is that this
	user-mode program defines _KERNEL, and relies on this bringing
	"struct file" and "struct socket" into scope, so simply
	not defining _KERNEL results in build errors as well.

	<sys/types.h> is also included before _KERNEL is defined, so
	the definition of boolean_t is not present, but putting
	_KERNEL further up front results in this build problem:

*** Failed target:  sock.o


	In short, this is a serious mess, and not something which is
	amenable to a simple point fix.

	
>How-To-Repeat:
	Try to (cross-)build NetBSD-current for vax; watch it fail.

>Fix:
	Sorry, none provided, but some apparent false starts above.
