Because Microsofts implementation of OpenGL, which is what you are using, needs some symbols to be defined which is found in windows.h.

GLee, GLEW, GLUT, SDL, and countless others can be used instead of windows.h. (actually, you need sdl_opengl.h, not sdl.h).

is there a way to use it cross platform without using any of the above such as
glut or other window system ? isn't it what openGL all about a cross platform?

i need to write my classes so there is a samll amount of change when i move to another platform... the graphic engine doesnt need to know that he is running under windows if he use openGL... right ?

OpenGL is a cross-platform API. It is not an OS abstraction layer. Unless you use it with an OS abstraction layer, your code will not be OS-independent. Check out SDL or GLFW.
