It's been a long standing issue that I can't seem to find a resolution
for: Fusion's use of nil. What can we do about it? Nothing? Do we
just let the user deal with it themselves (e.g. by #undef'ing).
I am somehow being compelled to succumb to the pressure. Mac folks
have been pleading for years now to rename struct nil to something
else. Unfortunately, it's part of the API: http://tinyurl.com/c3k7fgw
