error: expected specifier-qualifier-list before xxx (a structure )

when I try to define a LIST_NODE structure in a my code,
it's alert "error: expected specifier-qualifier-list before LIST_NODE", which following so many error info:

error: ‘LIST_NODE’ has no member named ‘next’error: ‘LIST_NODET’ has no member named ‘previous’error: ‘LIST_NODE’ has no member named ‘previous’

I was astonished for a minutes:

typedef struct LIST_NODE{   void   *data;   LIST_NODE   *next;   LIST_NODE   *previous;} LIST_NODE;

yeah, I found the error!
the structure is unnamed yet. I should gave it name so it can refer to itself
modified as follow, then erverthing would be ok:

typedef struct LIST_NODE{   void   *data;   struct LIST_NODE   *next;   struct LIST_NODE   *previous;} LIST_NODE;

good luck!
