Steps to reproduce:
- create a new application
- add C file with the following code:
#include <stdlib.h>

enum color { RED, YELLOW, GREEN, BLUE };
enum shape { CIRCLE, SQUARE, TRIANGLE };

struct cnode 
{
   enum color     paint;
   struct cnode*  next;
}

main()
{
   struct cnode  paintpot;
   struct cnode*  ptemp=0 ;
   enum shape  object;

   paintpot.paint = RED;
   paintpot.next  = ptemp;
   object = CIRCLE;
}

Result: A lot of unresolved identifiers red signs appear whereas the file can be built successfully.
To fix the problem a user should type semicolon after struct code definition:
struct cnode 
{
   enum color     paint;
   struct cnode*  next;
};
but without a semicolon it's still valid C code.
