That doesn't mean that g95 stayed stagnant behind. OK so it is still recommended to build it against gcc-4.0.3, but otherwise it is a fine compiler and I have only switched to gfortran in the gcc-4.4.x series when it had all the features that I needed for my work (outside of sage). > > I'm not sure at what point gfortran became the dominant compiler, but I've > not seen g95 used in the last few years.
