I think this will be a hard issue for a lot of people that need to support
industrial customers.

AbsInt will migrate to Red Hat/CentOS 7 for our builts to circumvent that, but I think
a lot of other people don't have this possibility.

For the xkbcommon thing: What me most disturbed is that it was removed during
a patch release. 5.12 did compile fine on CentOS 6.x, 5.12 did have it removed
and failed. That was kind of unexpected.

Greetings
