In PSDK/MinGW W32API the [lib]dinput[8].[a/lib] is really a combination 
of static and export library. It contains the 
DIDATAFORMAT/DIOBJECTDATAFORMAT defintions for joystick (c_dfDIJoystick, 
c_dfDIJoystick2), keyboard (c_dfDIKeyboard) and mouse (c_dfDIMouse, 
c_dfDIMouse2) that are compiled to every application using it.
