New Revision: 64133
URL: http://svn.boost.org/trac/boost/changeset/64133
Log:
setting up information passing system which will pass information from during parsing inside of the bitfield_element type's policy class for use in extracting infomration from the pointer later on. the infomration being stored must also be used for adjusting the mask which the hides the pointer
