Not at all.... By definition, glext.h defines all extensions present at the
time of generation of the file (as Wine's GL files, it's auto-generated from
the GL extension registry on SGI's CVS repository).

After, it's the job of the software to detect at run-time which extensions
are present, but can do a build supporting all of them even on a box which
only support GL 1.1 and no extensions at all.

It's a bit as if you said 'but why does the OSS .h files define AFMT_S16_LE,
my card only supports 8 bit sounds anyway'.

glext.h is only a header file, it's not a library.


PS: Raphael will laugh because he wanted to ship glext.h once and I said it
    was not a good idea :-))
