Wich libaray? There are many MPI libs, MPICH2, MS MPI, Open-MPI.
The Boost work with all libs and my project use only the boost.
The project file are linked against the boost and the boost link
against the MPI lib, but at compile time I don't know which lib is
used.

I need a flag at preprocessor time which shows the mpi support, because
I run into compile and link error if the is no mpi support enabled.
I include the boost/mpi.hpp but if there is no support I don't need  
include
the hpp
