If I understand the manual page correctly, LIST_END(head) is nothing
more than some portable way to handle sentinels at the end of the list.
Just smack the following code above the C file:

| #ifndef LIST_END
| #define LIST_END(head) NULL
| #endif

This is exactly the same as how it is defined in OpenBSD's sys/queue.h:
