The original code went to the trouble of converting endian-ness for 0, so I
thought it best to keep this in place. Who knows, perhaps some future
architecture will need it.
This was just incredible anal retentiveness on my part when I did the
original bi-endianness support. I think it can safely be changed to a
define so it gets optimized out properly due to constant folding in
the compiler.
