    GHC.Windows: more error support (guards, system error strings)
    
    This changes the output of throwGetLastError to include the system error
    message, rather than the message of our fictitious errno.
    
    It also adds several definitions to GHC.Windows, mostly from the Win32 package.
    The exceptions are:
    
     * getErrorMessage: returns a String, unlike in System.Win32.Types,
       where it returns an LPWSTR.
    
     * errCodeToIOError: new
    
     * c_maperrno_func: new
