It's most probably working because you are compiling on a newer system with a newer Visual Studio which has the newer math.h which has the function.
Older versions pre-2012 do not, hence the current non-usage.

Hey, I just realized we have an [atanh] object for cyclone, I actually did that one myself, and I just tested, it's working on windows!
here's the source https://github.com/porres/pd-cyclone/blob/master/cyclone_src/binaries/contro... https://github.com/porres/pd-cyclone/blob/master/cyclone_src/binaries/control/atanh.c
so, definitely, those functions may exist for windows, not sure what building system you're using, but it may need an update
