In C++0x, the construct member function of allocators has been changed 
to do perfect forwarding of their arguments.

The allocator defined by Boost.MPI does not do this, since it follows 
the C++03 way of defining allocators.

As far as I know, no versioning system was added in the standard to 
distinguish the two types of allocators.
A shame, since it leads to problems like this.
