I've been largely ignoring messages about perceived deficiencies in the current build system, given the consensus is to replace it anyway, but it seems to me that it has gotten better, not worse, in this respect. Almost all generated files are now put in dist* directories, which makes them easy to clean; and even if you do stop using a dist directory and it doesn't get cleaned, it's hard to see how files in such a directory could interfere with the build. Also, the existence of libraries/base/GHC/Prim.hs causing problems was pretty much unrelated to the build system. haddock behaves more-or-less like ghc --make, so haddocking the base library was picking up GHC/Prim.hs and GHC was getting confused by it. Short of copying all the sources into dist/ and haddocking them in there (which, incidentally, I think would be a good idea, although Duncan isn't keen), any build system would fail in the same way.
