Some platform used append and some use prepend, and it's likely because the maintainers needed one or the other for development. I'm not sure why you think I can't add the features in one go. It would be horrid to take Christophe's changes, then have to do basically all the same work a second time which is what Christophe's changes would force me to do. Say for example I implement this change only on one architecture. In that case the maintainer would be accepting a feature enhancement , but there would be no stopping it. I shouldn't have to go two strokes on one architecture, but each change I'm making is essentially a single architecture. They can go in all together or one at a time. Daniel
