I think that is a bit too much of a cavalier approach. For example, right now I am in the process of changing the compiler FreeBSD uses for Fortran packages from GCC 4.5 to 4.6 and 100% of the issues we run into are not related to Fortran but...C++. Breaking source code compatbility with a step like GCC 3 to GCC 4 is one thing, but constantly doing so with every release is just painful and makes as look bad. And it hinders the adoption of newer releases. Gerald
