-	NOTE: This entry might not compile when using modern compilers.
+NOTE: [Cody Boone Ferguson](/winners#Cody_Boone_Ferguson) fixed this for modern
+systems. There were two invalid operands to binary expression (`char *` and
+`void` and `int` and `void`) to resolve and a feature of the C pre-processor
+which no longer works had to be changed as well. In particular `#define C =G` in
+a macro to make `+=` and similar operators no longer works. The invalid operands
+to binary expressions were resolved with the comma operator. Thank you Cody for
+your assistance!
