I think we (and you) have been able to deal with compiler problems
reasonably well. I don't have a particular problem taking patches for
things like that. GCC is just an example of the problem.

My core point is that OpenBSD has made choices to build Mesa with
tools and versions no one else uses. If we want to add a new build
dependency not in OpenBSD's core, I don't think it's fair for
OpenBSD's choices prevent us from moving forward.

Huh? libglvnd is free software.
