Attached, find a new version of the macro AX_PROG_CXX_MPI to recognize an MPI
C++ compiler.

In the last version, the macro tested for the function MPI::Init. However,
this test never failed, as a C++ compiler will not try to link the function if
it is not actually called. Furthermore, the C++ bindings are deprecated in
current versions of MPI.
Therefore, the macro now tests for the C interface function "MPI_Init" as
"extern C"-function.
