New Revision: 47884
URL: http://svn.boost.org/trac/boost/changeset/47884

Log:
Made the Boost Build c++-template-depth feature be optional, thus avoiding a need to have each toolset module define its default value for this feature. This corrects a 'bug' with each such toolset module redefining the default value for all other toolsets as well. This also avoids a redundant command-line option from being passed to the compiler when this property is not specified.
