 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.
