New Revision: 55293
URL: http://svn.boost.org/trac/boost/changeset/55293

Log:
Split pointer_cast.hpp out of pointer_traits.hpp, and added
default implementations of generic_ptr::static/const/dynamic_pointer_cast
which perform ADL internally.

Added:
   sandbox/fmhess/boost/generic_ptr/pointer_cast.hpp   (contents, props changed)
