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 (in Patch 27). Others will need this for non-Intel solutions, it's really a part of the standard definition and should be shared. I can improve the commit message to make this explicit.
Yes that would help! And also move it to before it's usage so it clear that it is used in next one.
