Pointers and bitfields

what will be the output of the following code

	#include <stdio.h>
	struct test
	{
	unsigned int x;
	long int y: 33;
	unsigned int z;
	};
	int main()
	{
	struct test t;
	unsigned int *ptr1 = &t.y;
	unsigned int *ptr2 = &t.z;
	printf("%d", ptr2 - ptr1);
	return 0;
	}

the code creates compilation error , as you can not create a pointer to bit fields , simply because bit fields may not start at byte boundry
