/*  2. BYTE ORDER IN 32-BIT WORDS

To obtain the highest speed on processors with 32-bit words, this code 
needs to determine the order in which bytes are packed into such words.
The following block of code is an attempt to capture the most obvious 
ways in which various environemnts specify their endian definitions. 
It may well fail, in which case the definitions will need to be set by 
editing at the points marked **** EDIT HERE IF NECESSARY **** below.
