Cannot get open GL to run on Dev ++

Question

I am trying to run openGL on Dev C++. And I cannot get the code to run. I've tried everything on this site:

http://www.prinmath.com/csci5229/misc/DevC_OpenGL_for_Windows.pdf

My Operating system is windows 7-64 bit. I would use a different IDE if I could but my school insists that we use Dev C++.

here is the code that I am trying to run:

#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>    


void init()
{
    glClearColor (1.0, 1.0, 1.0, 0.0); 

    glMatrixMode (GL_PROJECTION);       
    gluOrtho2D (0.0, 200.0, 0.0, 200.0); 
}

void lineSegment()
{
    glClear (GL_COLOR_BUFFER_BIT);  // Clear display window. color buffer

    glColor3f (0.0, 0.0, 0.0);     
int p1 [ ] = {40,80};
int p2 [ ] = {160, 80};
int p3 [ ] = {100, 40};
int p4 [ ] = {100, 160};
int p5 [ ] = {0, 80};
int p6 [ ] = {200, 200};
int p7 [ ] = {100, 0};
int p8 [ ] = {100,200 };
int p9 [ ] = {30, 30};
int p10 [ ] = {0, 0};

glBegin(GL_LINE_LOOP);
glVertex2iv(p1);
glVertex2iv(p2);
glVertex2iv(p3);
glVertex2iv(p4);

    glFlush ( );     
}

int main(int argc, char *argv[])
{
    glutInit (&argc, argv);                         // Initialize GLUT.
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);   // Set display mode, single buffering.
    glutInitWindowPosition (50, 100);   // Set top-left display-window position.
    glutInitWindowSize (400, 300);      // Set display-window width and height.
    glutCreateWindow ("An Example OpenGL Program"); // Create display window.

    init( );                            // Execute initialization procedure.
    glutDisplayFunc (lineSegment);       // Send graphics to display window.
    glutMainLoop ( );                    // Display everything and wait.

    //return EXIT_SUCCESS();
    return 0;   
}

And here is what the compile log says When I try to compile:

Looks like you're linking with wrong version of C-runtime (CRT).

• If you have multiple versions of MinGW installed, show Dev-C++ where to find right includes and libs (check your PATH environment variable, MINGW_HOME environment variable and Dev-C++ compiler options). You must use CRT which ships with compiler.
• Try to #include <windows.h> before other includes. It can fix dllimports stuff
• Try to add -m32 flag to compiler command line (it will emit code for x86_32, in case if you are compiling with 64-bit compiler)
• Ask your teacher how to fix it (it's his (her) job, and it's (s)he who choose to use 10 years old stuff)

Note, that latest version of Dev-C++ was released 22.02.2005. It includes GCC 3.4.2 released September 6, 2004. You must really ask your teachers why would they insist on using 9 years old IDE with 10 years old compiler. You can find maintained version of Dev-C++ here (it was picked up by another developer), and latest MinGW compiler here.
