Comment (by mojca):

 I fixed (or know how to fix) approximately 9 errors in 4 files, but there
 are 19 more in the last file that I didn't yet look into. They are
 probably straightforward to fix though.

 I just didn't get the "fixes should be sent upstream" vs. "there's no
 value in patching any further" because those two statements seem to
 conflict with each other. I don't know if upstream would accept patches.
 It's slightly less relevant for us now that Ryan fixed the issue on the
 buildbot, but it might still be valuable if users could build from source
 out-of-the-box. What is not clear to me is how much maintenance burden
 patching might introduce in the future in case upstream rejects the
 patches. I would say that it might be worth trying with to get the patches
 upstream (with some low priority) or at least ask them for opinion
 upfront.
