* intel-cl tests: more rigorous detection of intent to use Intel Windows compilers
* fortran coarray test: make skipping more robust in that underlying MPI stack is .run()
This is useful for any Fortran coarray work, and especially for intel-cl where multiple Intel compiler
versions are often installed, and the wrong underlying MPI library may be dynamically linked,
and so a runtime check is needed to exercise the MPI stack underlying Fortran coarray.
This is done by
fc.run('sync all; end', dependencies: coarray)
* pep8
