新手！求助

新手，刚开始接触openGL,红宝书里的第二个例子double.c，编译什么的都没有问题，可就是有debug错误，以下为源代码：

#include <gl/glut.h>
#include <stdio.h>

static GLfloat spin =0.0;
void init(void)
{
glClearColor(0.0,0.0,0.0,0.0);
glShadeModel(GL_FLAT);
}

void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glRotatef(spin,0.0,0.0,1.0);
glColor3f(1.0,1.0,1.0);
glRectf(-25.0,-0,25.0,25.0,25.0);
glPopMatrix();
glutSwapBuffers();
}

void spinDisplay(void)
{
spin=spin+2.0;
if(spin>360.0)
spin=spin-360.0;
glutPostRedisplay();
}

void reshape(int w,int h)
{
glViewport(0,0,(GLsizei)w,(GLsizei)h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-50.0,50.0,-50.0,50.0,-1.0,1.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}

void mouse(int button,int state,int x,int y)
{
switch(button){
case GLUT_LEFT_BUTTON:
if(state==GLUT_DOWN)
glutIdleFunc(spinDisplay);
break;
case GLUT_MIDDLE_BUTTON:
if(state==GLUT_DOWN)
glutIdleFunc(NULL);
break;

default:
break;
}
}

int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGB);
glutInitWindowSize(250,250);
glutInitWindowPosition(100,100);
glutCreateWindow(argv[0]);
init();
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutMouseFunc(mouse);
glutMainLoop();
return 0;
}

会出现这样的提示：
The value of ESP was not properly saved across a function call.This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

大家都应该对红宝书和openGL比较了解了，求解~~
感激不尽！！
