Hi Arjen: Just to interject, you have been tempted before to go down this road of attempting to support gfortran-4.8. But I have always argued against that for the following reasons: We may never get that support to work properly. Adding such support introduces complexity into our new Fortran binding. gfortran-4.9 works beautifully, and modern Linux (and other) software distributions typically provide substantially higher versions than 4.9. So I assume those who are stuck with gfortran-4.8 or lower are a small and rapidly shrinking fraction of our potential Fortran users. So from the above considerations I believe we should address this issue by simply stating in the release notes that gfortran-4.8 does not work (unless the user specifies our old binding and examples using -DPL_DEPRECATED_f95=ON) and therefore gfortran-4.9 is the minimum version we support in undeprecated fashion going forward. @Hazen: Just for fun with all this testing power at your fingertips, do you want to specify -DPL_DEPRECATED_f95=ON for your gfortran-4.8 test to really make sure that works like I claim above?
