title: link redeclared as different kind of symbol in
body: <p>i have a objective-c program, i added a little lib with linked list in plain c.
  this is the header:</p>
  
  <pre><code>    typedef struct { int v; int w; } Edge;
  Edge EDGE(int, int);
  
  typedef enum tagTipoNodo {
      k_casellaPolozia,
      k_casellaKiller
  } tipoNodo;
  
  typedef struct node *link;
  struct node { int v; link next; };
  
  typedef struct node2v *link2v;
  struct node2v { int v; int val; link2v next; };
  link2v NEW2v(int v, int val, link2v next);
  void DEL2v(int v, link2v *lista);
  void Update2v(int v, int val, link2v lista);
  link sort2x(link2v lista);
  link sort2xDecr(link2v lista);
  int maxInList(link2v lista);
  
  
  struct graph { int V; int E; link *adj; int *tipo;};
  
  typedef struct graph *Graph;
  Graph GRAPHinit(int);
   void GRAPHinsertE(Graph, Edge);
   void GRAPHremoveE(Graph, Edge);
    int GRAPHedges(Edge [], Graph G);
  Graph GRAPHcopy(Graph);
   void GRAPHdestroy(Graph);
  
  void GRAPHShow(Graph G);
  void ingr();
  link nodeInDistance(Graph G, int A, int distance);
  link nodeInDistanceOfType(Graph G, int A, int distance, tipoNodo tipo);
  int distance(Graph G, int A, int B,tipoNodo tipo);
  int shortestPath(Graph G, int A, int B, tipoNodo tipo, int *percorso);
  link shortestPathList(Graph G, int A, int B, tipoNodo tipo);
  
  int distanceForAllocation(Graph G, int A, int B, tipoNodo tipo);
  void setPesoForNode(int n,int poliziotto);
  void resetPesoForNode(int poliziotto);
  void resetPesoForAllNodes();
  
  void initCasPoliz();
  link NEW(int v, link next);
  void DEL(int v, link *lista);
  link copyList(link l); 
  int lengthList(link l);
  int lengthListOfType(Graph G,link l,tipoNodo tipo);
  void deleteList(link *lista);
  int isPresentInList(link lista,int val);
  void printCaselleVietate();
  </code></pre>
  
  <p>in simulator all compiles well, but when i try to compile for device 
  this error occurs<br>
  link redeclared as different kind of symbol in...[...]
  how can i fix this?
  thanks</p>
