OpenGL: GL_TEXTURE_CUBE_MAP and GL_REFLECTION_MAP

Question

I am currently working on a project in OpenGL. Every time I try to reference GL_TEXTURE_CUBE_MAP and GL_REFLECTION_MAP they appear to me as undefined. I have included gl.h, glu.h, and glut.h, but they still appear undefined. Any suggestions?

Everything beyond OpenGL-1.1 is not part of the OS ABI (binary interface) specifications on Windows and OpenGL-1.2 on GLX (Linux is about due to get a revised OpenGL ABI)

Anything beyond that functionality must be loaded at runtime through the extension loading mechanism , even if it is core functionality. Most easy done by using the GLEW library.
