Since Chris Torek was suggesting that YOU should #define KBYTES
it is hardly surprising that the macro doesn't already exist.

If the only thing you want is ctob() (or PGSHIFT or NBPG) it suffices
to get it from <machine/param.h> (which <sys/param.h> includes).
That's where they are in SunOS 3.2 and on a Sequent. 
So the two lines YOU have to write to define KBYTES are
	#include <machine/param.h>
And (
	#define KBYTES(size) (ctob(size) >> 10)
Or
	#define KBYTES(size) ((size)*NBPG/1024)
)
