Yeah, now that you point it out, macros.hpp is definitely the wrong place for it.
I personally don’t care for the dumping ground that is globalDefinitions.hpp and
would prefer smaller and more focused headers, but that’s an entirely different
discussion.  I’ll move this new macro there and clean up the patch accordingly
(there are #include changes that will need adjusting).
