I will look into them as soon as I am able. Oops, I meant to write a bit more here before sending. You will need to do a clean build in order for the dependencies to actually take effect. In this approach, dependencies are computed as a side effect of the build -- but obviously that was not true before the patch series. So, after you update, you effectively have no dependencies. If you look in the tree you will see there are still dependencies for host objects and in various t-* files in config/. The latter are easy to convert; see the "t-i386" and "t-glibc" patches. The key is to ensure that (1) dependencies are in fact created (search the .deps directory), (2) dependencies are used (see the DEPFILES code at the end of gcc/Makefile.in), and (3) any generated files are either in generated_files or have an explicit dependency (the t-i386 change has an example of the latter). I don't plan to convert the host objects. However I think it isn't extremely hard, following the existing model. thanks, Tom
