You could move this before 9/15 of your series so you don't need to
duplicate the macro in 9/15.

And also (wanted to comment this to 9/15 but OK here as well) the macro
is prone to overflows. Not yet sure what the impact would be apart from
failing the detection if it is in a range or not. If it lives in ctree.h
this fact at least needs documentation, I guess.
