When compiling mpi.h with a modern C++ compiler and a high degree of pickyness (e.g., -Wold-style-cast), casting using (void*) in the OMPI_PREDEFINED_GLOBAL and MPI_STATUS*_IGNORE macros will emit warnings. So if we're compiling with a C++ compiler, use C++'s static_cast<> instead of (void*). Thanks to @shadow-fax for identifying the issue.
