Re: failure building gnustep cairo backend, and gnustep-examples on OpenBSD sparc

[Fred Kiefer]

Judging from the error message you are getting there could be two 
different reasons for the problem.

- Either the compiler has an issue with seeing "id" used as a variable name.

- Or, GLuint isn't defined at this place.

I currently don't have GL properly installed on my machine, so I cannot 
check here.
