No one wants to manually do dependency management in even a moderately sized project. I really haven't found an ideal way to have these -MM -MT flags integrated into Makefiles; I've tried having an awk script automatically modify the Makefile as the build is happening, but of course the updated dependencies will only work for later builds, so it's only good for updating the dependencies. Any other approaches HNers used and really liked?
