Confirmed to compile on latest stable arduino IDE v1.8.15 on windows. What version IDE and OS are you using? Also looks like its failing on stdbool.h because the new arduino is redefining boolean values. Then try commenting out all #include <stdbool.h>.

Not sure how to fix this exactly.

It appears the Arduino IDE in my stable repo was very out of date.
