    mesa: update glext.h to version 81

I double checked the bisect, and also reverting this commit from master fixes it.
This is up to date Fedora 17, gcc (GCC) 4.7.0 20120507 (Red Hat 4.7.0-5),

Looks like you just have an invalid .o file in your repo.  Try make clean and make again.

Actually it doesn't help, sorry for not mentioning this earlier. I did try make clean, make distclean, git clean -fdx, git reset --hard, none of this helps. Only reverting the mentioned commit helps.

Are you using ccache or something like that? If so, the object file might be corrupted in the cache.

Yeah, corrupted ccache was the issue, thanks for help and sorry for the false alarm.
