hi, trying to use this tutorial (http://www.opengl-tutorial.org/beginners-tutorials/) on 64-bit windows 8 with netbeans and cygwin 4.8.1.

this occurs many times, but the first on is on this line: void APIENTRY gluQuadricCallback(GLUquadric *qobj,GLenum which,void (CALLBACK *fn)());

any pointers will be appreciated.

thanks
