As far as I've experienced and understand it, it doesn't - it's more
that GHC can detect when Haskell modules don't need recompiling while
the same is not true for C or C++ sources. For example, I change one
module and see GHC report only that module and its dependents being
recompiled, while the other compiled modules are reused from previous
'cabal install' runs. The "C-sources:" are recompiled every time even
if unchanged, which I too find it somewhat annoying even with my small

I think becausae the clean hook is probably not called by 'cabal
install', but by 'cabal clean'.
