In UnwindCursor.hpp, include config.h before checking
Include libunwind_ext.h for UNW_STEP_SUCCESS.
On second thought, maybe I don't actually need this change, and the includes still seem like a mess in libunwind. Maybe it makes more sense to do a larger revision eventually.
This seems relatively harmless, not sure if its valuable though.
... so that it no longer shows on my review queue. I think this is still worth doing, especially the weird include places in UnwindCursor.hpp might confuse readers.
