Hi Gavin,

Just to be clear, is it just "using namespace boost;" I need to worry about,
or do I also need to strip out entries like "using namespace
boost::filesystem;"?

Best wishes.

Tim Burgess

Make sure you don't have "using namespace boost;" inside any header files
(unless within method scope), and if you have it in source files, ensure it
only appears after all #includes.

(Then also follow this rule for any "using namespace" statements, because
they may eventually bite you similarly.)
