Missing (or bad) header file: HsWin32.h

Hi, when I try `cabal install` I get this error:

```
Configuring Win32-2.3.1.0...
cabal: Missing dependencies on foreign libraries:
* Missing (or bad) header file: HsWin32.h
* Missing C libraries: user32, gdi32, winmm, advapi32, shell32, shfolder
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
Failed to install Win32-2.3.1.0
cabal: Error: some packages failed to install:
Win32-2.3.1.0 failed during the configure step. The exception was:
ExitFailure 1
```

So I try `cabal install --extra-include-dirs=~/win32/include --extra-lib-dirs=/usr/i686-w64-mingw32/lib`, but it gives the same error.

I'm trying to install this because of this: https://ghc.haskell.org/trac/ghc/ticket/10070

Start by reproducing the Win32-2.3.1.0 configure failure with the reported include and library paths, then inspect the HsWin32.h check and the listed Windows libraries. Done means identifying whether the header or libraries are missing, incompatible, or incorrectly located and documenting a verified installation path.
