When I lint the following on a Ridge 32C under ROS 3.3 (SYSV derivative), 

	#include <stdio.h>

	main() {
	static int page;

	ioctl(0,2,(char *)(&page));
	}

I get

test.c
==============
(7)  warning: main() returns random value to invocation environment


==============
function returns value which is always ignored
    ioctl	

Note that there are no pointer complaints.  Sounds like you have a problem
on your system.  If lint complains about the sample above, I would complain
to the vender.
