[mpich-discuss] test/mpi/dtpools/configure bashism

Hello, unfortunately mpich 3.3.1 configure does not run in BSD env: ./configure: types+=MPI_CHAR,: not found and so forth, please see attached build output log for more info. I've prepared a patch to test/mpi/dtpools/configure.ac to use portable sed syntax instead of the bash subshell syntax which is causing problems in this case. Regards, Thomas
