There was a special catch about these globals, but i can't remember right now.

However, I think this will break builds on Windows when FLEXT_INLINE is defined. A better solution would be to either remove FLEXT_INLINE entirely or use the FLEXT_TEMPLATE macros, but I couldn’t really understand those or get them to work.
