| | 4 | === Compilation with gfortran fails because of unrecognized command line option `-fallow-argument-mismatch` === |
| | 5 | |
| | 6 | If this happens, please delete this option in the compile include file in `make.arch`. This option is necessary for compilation with gfortran 10, but older versions of gfortran don't seem to even know this option. |

| | 8 | === Compilation with gfortran fails with an error about a `Type mismatch` related to MPI_allreduce or some other MPI function === |
| | 9 | |
| | 10 | If this happens, please specifcy `-fallow-argument-mismatch` in the compile include file in `make.arch` in the line 'OPT = ....'. |
