These cases are comparitively rare

#if BOOST_CXX_FOO >= BOOST_VERSION_NUMBER(2,0,0)  \
    && BOOST_CXX_FOO < BOOST_VERSION_NUMBER(3,0,0)

> or 'if major=3 and minor>2', so I'd rather need BOOST_CXX_FOO_MAJOR etc.

#if BOOST_CXX_FOO >= BOOST_VERSION_NUMBER(3,2,0)  \
    && BOOST_CXX_FOO < BOOST_VERSION_NUMBER(4,0,0)
