Sparse 0.4.3 was released on 2010-11-02. From the release announcement: Mostly small fix up. It can parse the recent kernel better, less noise. For people interested in the sparse internals, there is a sparse inspecting tools now. Currently it has limited knowledge of AST. It is very easy to extent though. The mentioned "sparse inspecting tool" has an automagic dependency on GTK+. Other than that, renaming the 0.4.2 ebuild seems to work.
