+ * Could have been named NUXI-endian
+ * This file *should* work, but has not been tested.
+ * It's the beginning of what vaxlinux implementers will have to do.
+ * I just hope we won't have to write standardized cpu_to_ve32() and suches!
+ * little endian is 1234; bigendian is 4321; vaxendian is 3412
+ *
+ * But what does a __u64 look like: is it 34127856 or 78563412 ???
+ * I don't dare imagine! Hence, no 64-bit byteorder support yet.
