cad/NASTRAN-95: mark broken
Recent changes in gfortran seem to have broken this port so that it doesn't
produce valid results anymore. See  for more details.
This port would likely be a good candidate for LLVM Fortran but I currently
don't have time for to try (patches welcome).
Use dos2unix, as it seems necessary but not sufficient for a future fix.
Pet portlint while here.
