- * Could have been named NUXI-endian, but we use the same name as in glibc.
- * hopefully only the PDP and its evolutions (old VAXen in compatibility mode)
- * should ever use this braindead byteorder.
- * This file *should* work, but has not been tested.
- *
- * little-endian is 1234; big-endian is 4321; nuxi/pdp-endian is 3412
- *
- * I thought vaxen were NUXI-endian, but was told they were correct-endian
- * (little-endian), though indeed there existed NUXI-endian machines
- * (DEC PDP-11 and old VAXen in compatibility mode).
- * This makes this file a bit useless, but as a proof-of-concept.
- *
- * But what does a __u64 look like: is it 34127856 or 78563412 ???
- * I don't dare imagine! Hence, no 64-bit byteorder support yet.
- * Hopefully, there 64-bit pdp-endian support shouldn't ever be required.
