[Cin] configure.ac update

[Andrea paz]

I always have to do an autoupdate with Arch too. Anyway, can you
compile in Manjaro then? The problem of not being able to build from
git came back to me.

You could give commands:
sudo pacman -Qqetn > pkglist.txt
sudo pacman -Qqem > aurlist.txt
and post them here, so I can understand if there are differences in
packages and versions between Manjaro and Arch?
