#5538: boost.mpi miscompiles with gcc4.6 and option -std=c++0x
 Reporter: christophe.prudhomme@… | Owner: dgregor
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: mpi
  Version: Boost 1.46.1 | Severity: Regression
 Keywords: mpi stdc=c++0x |

 boost.mpi with gcc-4.6 and the option -std=c++0x don't get well together
 here is a very simple example

 ----- t.cpp
 #include <boost/mpi.hpp>
 ------ end of t.cpp

  the issue arises with the use of the -std=c++0x flag to use
 the new c++ standard. It use to work properly with previous g++ version

 compile without -std=c++0x
 g++ -I/usr/include/mpi -c t.cpp
 no errors

 try compiling with -std=c++0x
  g++ -I/usr/include/mpi -std=c++0x -c t.cpp
