Hmmm, I think there was someone who was looking at this, but I don't
recall who it was.

Given that Linux runs on both big and little-endian machines, yes the
endian issues have largely been addressed, with the exception of some

It would depend on how much needed to be changed just for the benefit
of the LE machines, and how much it would complicate future
maintenance of the rest of the code. If there are suddenly lots of
places where we have to do things differently now because of the
existence of the LE port, then that would make it easy for people to
break things in the future without realizing, and that would be a
reason for rejection.
I am not opposed to LE support but I would be opposed to large-scale
changes to the code for the sake of one platform which isn't widely
used - unless of course you can argue that the changes result in us
doing things the "right" way for all platforms.
It ultimately comes down to "show us the code".
