FWIW, the one I came up with was:

int main(void)
{
	union {
		unsigned int val;
		unsigned char val_bytes[4];
	} endian_test;
	unsigned short *p;
	unsigned int test_val;
	int big_endian = 0;

	endian_test.val = 0x01020304;
	if (endian_test.val_bytes[0] == 0x01)
		big_endian = 1;

	p = (unsigned short *) &endian_test.val_bytes[1];
	*p = 0x0506;

	if (big_endian)
		test_val = 0x01050604;
	else
		test_val = 0x01060504;

	if (endian_test.val != test_val)
		return 1;

	return 0;
}
