New description:

 boost/detail/endian.hpp fails to autodetect endianess for Android and Xbox
 so __LITTLE_ENDIAN__ or __BIG_ENDIAN__ (respectively) has to be manually
 defined before anything includes that header.
 Alternatively, a more elaborate approach can be used:
 {{{
     #if defined( __ANDROID__ )
         // http://stackoverflow.com/questions/6212951/endianness-of-

 android-ndk
         #include "machine/_types.h"
         #ifdef __ARMEB__
             #define __BIG_ENDIAN__
         #else
             #define __LITTLE_ENDIAN__
         #endif // __ARMEB__
     #elif defined( _XBOX ) && !defined( __BIG_ENDIAN__ )
         #define __BIG_ENDIAN__
     #endif // platform
 }}}
