This looks like it should be fixed by requiring gfortran >= 10 on the
libmpich-dev control, yes?
Sorry I'm slow in responding - on holiday

Thanks Jed. I think you're replying here in response to discussion
raised elsewhere. Could you provide a url link if its publicly

in practice. It was evidently built with gfortran-10, but depends on
gfortran-9, which doesn't recognize these arguments.

This can be worked around if one has gfortran-10 installed:
$ MPICH_CC=gfortran-10 mpifort a.f90
$
$ mpifort -show
f95 -O2
