Hi,

I was thinking of submitting a review, tried to build the library  
with gcc-4.2.4, and ran into this error. I apologize in advance if  
this has already been discussed / resolved, I haven't been following  
the discussion.

The tar ball was named RC4 and was laid down over Boost trunk in case  
that matters.

Here's the program I was trying to compile.

#include <iostream>
#include <stdexcept>
#include "mpi.h"
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>

int main (int argc, char *argv[])
{
   try {
     boost::log::sources::logger lg;
     MPI_Init(&argc, &argv);
     int rank = 0;
     MPI_Comm_rank(MPI_COMM_WORLD, &rank);
     BOOST_LOG(lg) << "hello from processor " << rank << "\n";
     MPI_Finalize();
   }
   catch (std::exception& e) {
     std::cout << e.what() << std::endl;
   }
   catch (...) {
   }
   return 0;
}
