Just do it the old fashioned way!

typedef enum {
  ntTile,
  ntEnemy,
  ntLevel
} NODETYPE;

typedef struct _tagNode {
    NODETYPE nNodeType;
    void  *pItem;
    struct _tagNode  *pNext;
} NODE, *LPNODE;

Then you just create structures for holding all your different node types
and when you walk down the list you cast the void pointer to whatever type
the nNodeType indicates.  Voila!  Generic linked list in C.  :)
