Description

If you build the Paths_pkgname module that Cabal generates on windows then you get these kinds of warnings: 

dist\build\autogen/Paths_cabal_install.hs:12:0:
    Warning: Module `Data.Maybe' is imported, but nothing from it is used,
               except perhaps instances visible in `Data.Maybe'
             To suppress this warning, use: import Data.Maybe()

dist\build\autogen/Paths_cabal_install.hs:19:0:
    Warning: Definition but no type signature for `prefix'
             Inferred type: prefix :: [Char]

dist\build\autogen/Paths_cabal_install.hs:20:0:
    Warning: Definition but no type signature for `bindirrel'
             Inferred type: bindirrel :: [Char]

dist\build\autogen/Paths_cabal_install.hs:73:14:
    Warning: This binding for `p' shadows an existing binding
             In a case alternative

dist\build\autogen/Paths_cabal_install.hs:80:9:
    Warning: This binding for `path' shadows an existing binding
             In a case alternative

It'd be nice if we generated code that gave no warnings so that people could make -Wall clean packages on Windows.
