OpenGL rotation of merry-go-round

[cowcow8866]

I have rendered a merry-go-round in the following code. However, when I set rotation, it just gives me rotation of the whole thing around the y-axis but not a self-rotation. My question is how can I change the following code to give self-rotation (either clockwise or counter-clockwise) but not rotation of the whole thing around the y-axis.
The code that gives rotation is in the third paragraph in the line glRotatef(angle,0.0f, 1.0f, 0.0f); The idle function is just let the angle +1 degree. If the angle exceeds 360 degrees, then minus 360 degrees.
Than You.
