Error while trying to use OpenGL

I have a very simple C code in which I am trying to use OpenGl. When I include the following files

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

I get the following error(and many more but they are similar): C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\include\GL/gl.h(1152) : error C2144: syntax error : 'void' should be preceded by ';'

but when I include

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

I get the following error \mainfile.cpp(4) : fatal error C1083: Cannot open include file: 'GL/glut.h': No such file or directory

any idea what is happening?

I am using XP, VS2005

Per this other answer you do need windows.h first.

On my SDK (v7.0a) there is no glut.h, just gl.h and glu.h. 

 Directory of C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include\gl


04/26/2011  05:00 PM    <DIR>          .
04/26/2011  05:00 PM    <DIR>          ..
09/30/2009  08:27 PM            69,085 GL.h
09/30/2009  08:27 PM            18,284 GLU.h
               2 File(s)         87,369 bytes
               2 Dir(s)  191,961,296,896 bytes free

Looks to me like you have to install the other header file by hand, per instructions here.

GLUT isn't part of OpenGL. You need to install it, which is what that error says.
