From here: http://www.opengl.org/wiki/Getting_started#OpenGL_2.0.2B_and_extensions

For Linux: http://www.opengl.org/registry/api/glext.h

For GLX: http://www.opengl.org/registry/api/glxext.h

For Windows: http://www.opengl.org/registry/api/wglext.h

Answer 2

For easier access to OpenGL extensions (inc. constant values and function bindings) you can either use glew or glee. Interfaces in both of these libraries are similar. Glew provides access to the newest OpenGL extensions and core specifications.
