Hi,

don't forget to maintain the BOOST_NO_0X for users backward 
compatibility and change the doc to state that these macros are 
deprecated and that will be removed e.g. 4 versions later.

A macro to don't provide them as BOOST_CONFIG_DONT_PROVIDE_0X_MACROS 
will be useful also, to ensure we don't use them during the deprecated 
period.

Best,
Vicente
