--- Comment #4 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Just need to edit the trunk/libgfortran/libtool-version file, bumping the major rev number and build from a clean build directory. I have tested this and it works fine. I want to see if we are going to get the fortran-dev branch in or not for 7. I only see a handful of testsuite failures there.
