Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/*

|
* 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.
