-### To run:
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this entry to
+work with clang which is stricter on the type of args to main(). Curiously
+although clang requires the types of args to be strictly correct it allows for
+only one arg which he made it as the second arg was not used and this allows for
+a closer match to the original format of the entry. Thank you Cody for your
+assistance!
