If ever I need this (and I don't see why I would since
fread/fwrite deals with endian issues for me), how
would I use it?  Do I need to test both conditions as
in the following:

     if octave_config_info("words_little_endian")
	do little endian stuff
     elseif octave_config_info("words_big_endian")
	do big endian stuff
     else
	error("not little endian or big endian")
     endif

Thanks,
