Thanks pablo, I've applied your changes to libosmocore, tagged it as 0.3.0 and applied the changes to openbsc. I'm now manually fixing up libosmo-sccp, osmo-tetra, cemmlgr-ng and other projects that all refer to libosmocore. I would appreciate if you could take care of osmcoom-bb.

I will take care of that, of course.
