Will, as far as I know, give you a BYTE_ORDER definition on those
systems that define BYTE_ORDER (AIX, BSD, Linux, Mac OS X, OSF/1) but
not all systems do (Solaris has _LITTLE_ENDIAN or _BIG_ENDIAN defines in
<limits.h>, but no BYTE_ORDER).
On other systems you will, as far as I know have to use some other
method to determine endianness.
