So these arrays actually have to be exported? In the current (5.2) sources they
seem to only be used in stream.c, maybe make them static there?

yes, they need to be exported, they are used by the allocation algorithm

Others will need this for non-Intel solutions, it's really a part of the
standard definition and should be shared.
