No.

"glext.h" is NOT linked to any linux distribution/version. His purpose is to
declare all the possible extensions of any graphic hardware. For that
reason, SGI handles the "official" glext.h, which you can retrieve from:

For now, we do not really use the version 7 of the header, but this will
come soon (for fututre new extensions such as NV20 ones), so the only thing
you must do, is to get and replace the glext.h.
