#include "build/build_config.h"

key_system_properties.h needs this too.

Both done (I guess we were picking them up accidentally through
key_system_info.h)

As in a previous CL, do we need all these comments for overrides?
If anything, you would want to describe unique properties of this class's
implementation.

Agreed, removed.
