That however causes a:
TestGLUT: fatal error: GLUT_CBWindow_d7Tf: uncaught exception
This is because GHC implements exit using an exception that is caught outside the main program - GHC's implementation of exitWith just doesn't work with callbacks.
As a workaround I suggest importing shutdownHaskellAndExit from the run-time system:
foreign import shutdownHaskellAndExit :: Int -> IO ()
This seems to do the trick. Thanks alot! /Calle
