Where can I download glext.h?

Hi, I’m using MSVC++ 6.0. From the forum, I gather that it does not include “glext.h” which I need for multitexturing, right?

I tried to search google, nvdia website, and even followed links from previous posts on the forum, but to no avail.

Please help me if you can.
If you know of any place where I can download this header file, pls reply?
Thanks alot.
