Boost.Test does not provide means to do this directly. You can alsays 
mimic some
kind of singleton though:

struct GlobalFixure {
   GlobalFixure*& instance() { static GlobalFixure* s_inst = 0; return 
s_inst; }

   GlobalFixure()
   {
       instance() = this;
       ...
   }
};

...

GlobalFixure::instance().m_member.do_something();

Is this approach used as a global fixture or a test fixture?

Thanks Simon
