 * @bug 8280963
 * @summary "%-16lu" formatting string is used to format uintx (uintptr_t)
 *          flag values for output. uintx is 64-bit on win64, and "lu" format
 *          is intended to be used with unsigned long that is 32-bit on win64.
 *          Thus flag values that are exact multiple of 4 GiB will be formatted
 *          into 0 in PrintFlags output.
