Given that the difference only appeared on animals that David pointed
out have big-endian architecture, it seems we'd only need two output
files.  It does seem true that the extended hashing functions  that
were adding to support partitioning would somehow be affected by

Thank you David for creating the patches and Andres for committing it.
