PS4: 
I had a thought lately about such updates with potential, hard to
predict side-effects: We could set some more strict requirements
after the next release (1.3). I have already C11 and libpci >=
3.0.0 on my wishlist. We could get rid of some more ugliness,
but I'd feel better not to do it 1.5 years after the last release.
