Hi Timur,

Can this be true?

I would assume a software constructed data structure would be in
host-endian mode. The only reason to be concerned with endianness is if
you are transmitting binary over some communications medium, or sending
something to hardware (which in rare circumstances may not be host-endian).

Throwing in macros that will always be discarded (if this host is
bigendian) seems unnecessary.

Regards, Steve

An urelated change should probably be in a new patch.
