   Because Little-Endian architectures are most common,
29
   we only set SHA1DC_BIGENDIAN if one of these conditions is met.
30 31 32 33 34
   Note that all MSFT platforms are little endian,
   so none of these will be defined under the MSC compiler.
   If you are compiling on a big endian platform and your compiler does not define one of these,
   you will have to add whatever macros your tool chain defines to indicate Big-Endianness.
