[ Christophe Prud'homme ]
* Bug fix: "libboost-wave-dev: Dependency on libboost-filesystem-dev
  missing", thanks to Martin v . Löwis (Closes: #346367).

[ Domenico Andreoli ]
* boost/graph/topological_sort.hpp: removed name of unused parameter
  to prevent long compiler warning.  Closes: #347519.
* Applied patch from upstream CVS to fix parsing of valid options
  with a common root.  Closes: #345714.
* libboost-python-dev now correctly depends on python2.4-dev.
