[mpich-discuss] Errors building MPICH on Windows 10 Ubuntu subsystem

[Jeff Hammond]

Because OpenCoarrays calls MPI from C, the possible Fortran ABI variation
across major versions of GCC should not be an issue.  Damian should be fine
to apt-get install mpich and then use the resulting C library.  I imagine
that cafc='mpicc -cc=gfortran-6' would work, but this is just a guess.

Intel recently approved Windows 10.  If I can get the VM for this, I'll try
to debug this.
