/* The following tests optimise behaviour on little-endian
machines, where there is no need to reverse the byte order
of 32 bit words in the MD5 computation. By default,
HIGHFIRST is defined, which indicates we're running on a
big-endian (most significant byte first) machine, on which
the byteReverse function in md5.c must be invoked. However,
byteReverse is coded in such a way that it is an identity
function when run on a little-endian machine, so calling it
on such a platform causes no harm apart from wasting time.
If the platform is known to be little-endian, we speed
things up by undefining HIGHFIRST, which defines
byteReverse as a null macro. Doing things in this manner
insures we work on new platforms regardless of their byte
order. */
