int main(void) {
	printf("Size of an unsigned long is %d bytes\n",sizeof(unsigned long));
	return(0);
}

That simple program will tell you that an unsigned long is 4 bytes, or 8
bytes.

It is then a safe assumption - that if you get back '8', that you're
running a 64bit kernel, on a 64bit processor.
