libstdc++5-devel-5.3.1-alt9.x86_64	arch-dep-package-has-big-usr-share	info	The package has a significant amount of architecture-independent data in /usr/share, while it is an architecture-dependent package. This is wasteful of mirror space and bandwidth, as we then end up with multiple copies of this data, one for each architecture. If the data in /usr/share is not architecture-independent, it is a policy violation, and in this case, you should move that data elsewhere.;
