MPI_Info_get and MPI_Info_get_valuelen were deprecated in MPI-4.0 (replaced by MPI_Info_get_string). When building IMB against an MPI implementation that marks these with [[deprecated]] attributes (e.g., OpenMPI main v6.1.0a1), compilation fails under -Werror=deprecated-declarations. Add a #if MPI_VERSION >= 4 gate in IMB_print_info() to use MPI_Info_get_string on MPI-4.0+ while preserving the original calls for older implementations.
