I spent five minutes on my version. Yours has to be better.

Sounds fine to me. BTW that code had some bugs in it (I checked in a
fix) and I copied it from dri/common. I should see if common has the

I'm not using it. I think the body for it was still in eglapi.c and I
added it to the h file make the compiler stop complaining. Fine with
me to delete it again.
