though there are no C++ bindings for oshmem, we need C++ wrappers
since a C compiler might not be able to compile a C++ source.
the C++ wrappers are :
- shmemc++ / oshc++
- shmemcxx / oshcxx
- shmemCC / oshCC (on case sensitive filesystems)
also add the examples/hello_oshmem_cxx.cc example
Thanks Bert Wesarg for bringing this to our attention
