+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this but he
+observed that sometimes the program asks the user to hit return a second time to
+resume solving the maze. It does not always happen. It doesn't seem to be
+related to making it work under macOS as all that did was removing some invalid
+prototypes and use `printf()` instead of the invalid pointer to it (incompatible
+type).
