    \brief Use external 64-bit integer types.

    RapidJSON requires the 64-bit integer types \c int64_t and  \c uint64_t types
    to be available at global scope.

    If users have their own definition, define RAPIDJSON_NO_INT64DEFINE to
    prevent RapidJSON from defining its own types.

    GCC 4.6 provided macro for detecting endianness of the target machine. But other
    compilers may not have this. User can define RAPIDJSON_ENDIAN to either
    \ref RAPIDJSON_LITTLEENDIAN or \ref RAPIDJSON_BIGENDIAN.

    Default detection implemented with reference to
    \li https://gcc.gnu.org/onlinedocs/gcc-4.6.0/cpp/Common-Predefined-Macros.html
    \li http://www.boost.org/doc/libs/1_42_0/boost/detail/endian.hpp
