What is the official boost macro to determine endianess?
And what is the header to include to get it?

I cannot find any help in the documentation of boost.endian but I can
find those macros by grepping in boost:

BOOST_LITTLE_ENDIAN, BOOST_BIG_ENDIAN, BOOST_ENDIAN_BIG_BYTE,
BOOST_ENDIAN_BIG_WORD, BOOST_ENDIAN_LITTLE_BYTE,
BOOST_ENDIAN_LITTLE_WORD, BOOST_PDP_ENDIAN

Thanks,

Frédéric
