@code{__BYTE_ORDER__} is defined to one of the values
@code{__ORDER_LITTLE_ENDIAN__}, @code{__ORDER_BIG_ENDIAN__}, or
@code{__ORDER_PDP_ENDIAN__} to reflect the layout of multi-byte and
multi-word quantities in memory. If @code{__BYTE_ORDER__} is equal to
@code{__ORDER_LITTLE_ENDIAN__} or @code{__ORDER_BIG_ENDIAN__}, then
multi-byte and multi-word quantities are laid out identically: the
byte (word) at the lowest address is the least significant or most
significant byte (word) of the quantity, respectively. If
@code{__BYTE_ORDER__} is equal to @code{__ORDER_PDP_ENDIAN__}, then
bytes in 16-bit words are laid out in a little-endian fashion, whereas
the 16-bit subwords of a 32-bit quantity are laid out in big-endian
fashion.
