I originally did something similar:

---
#define BOOST_TEST_MODULE foo
#include <boost/test/auto_unit_test.hpp>
#include <fstream>
#include <iostream>
using namespace boost::unit_test;
struct output_setup {
    output_setup()
    {
        logStream_.open( "c:\\temp\\log.xml" );
        if (logStream_.is_open())
          unit_test_log.set_stream( logStream_ );
   }
    ~output_setup()
    {
         if (logStream_.is_open())
          unit_test_log.set_stream( std::cout );
   }
   std::ofstream logStream_;
};
BOOST_GLOBAL_FIXTURE( output_setup );
---
The above kind-of works, but the final "</TestLog>" goes to stdout (which 
was unexpected, at least for me). I understand what happens, but wouldn't it 
be more intuitive to have the above working?
OTOH, defining the output_setup instance as a static instance:
output_setup g_outputSetup;
seems to work just fine though, and does not require 1.34 either.
