Again, my preference would be to have the committed files match flang with its default options.    When testing other compilers, or other option sets, the appropriate value could be supplied through CMake.

Ok, thanks for chiming in! I'm just going to update the reference outputs to match what flang does, and we can worry about gfortran later.
