 Replying to [comment:20 kencu]:

 Endian, the others are Big Endian).

 I thought to try, because a) not a big deal of effort even if wasted
 anyway, b) some cases of code may be mostly identical (judging from
 examples, not from real knowledge).

 Yes, I know. I wanted to make it :)

 Somehow I did not find an option to turn them off completely. What I did
 try initially is using `pthread` type coroutine, and that led to freezing
 in the mid of test suite (could be because my `pthread` patch has an
 error).

 I will try it now.
