RE: [boost] [guidelines suggestion] boost-wide debug support

Hi, 

it think, it is good to be able to turn on debugging for the one library
only, at least sometimes, and to to have the debugging output from all.

I would not get rid of local debugging macros completely - thy could be
defined according to the global presence of BOOST_DEBUG, e.g.
Then, one can easily control the full debug output with BOOST_DEBUG
or refine the configuration with a separate BOOST_XXX_DEBUG.

Do you see it sensible?
