Tested your patch, the warnings are gone. A couple of apps tested, seems to work.
I don't have a machine where it would cause aborts.
Additionally, the typo fix (which I found in upstream already fixed) also prevents the
Git checkout at configure stage. The revision bump might not be needed, as no packages
could have been built, but someone might have manually built it?
OK?
