	..because the <sys/param.h>  does include the <linux/limits.h>
	unconditionally at its begin..

	(At least with my libc-5.3.0 -- I know, it is bleeding-edge-
	 stuff... -- oops, GDBM is not anymore at the libc ...)

	Umm.. 4.5.26 (Dec-93) doesn't do that unconditional include..
	(yeah, I found one old machine..)

	.. and libc version dependent :-/  You have 4.x ?
