Well, I can't do any reasonable GUB-fixing, it's out of my depth.

Also, your relevant patches are out of my depth as well. Though,
nobody objected during review, thus I think we should keep them.

But I happily test things :)
Right now I try a GUB-build from a local branch containing nothing
else than already released 2.19.83. (with said gublbb and most recent
GUB)
If it fails (it worked half a year ago), than I suspect a GUB-problem.
And I may try to bisect GUB, although this will be very tedious...
If success I may try going lilypond-upstream.

Cheers,
