New Revision: 85272
URL: http://svn.boost.org/trac/boost/changeset/85272

Log:
Bump minimum compiler requirements.

This requirements bump will allow increasing modularization of
the boost libraries. This change is still extremely conservative. To
allow proper modularization, the version requirements should be
increased much more.

(from Stephen Kelly)
