          Issue ID: 21972
           Summary: importC: Error: no struct-declarator-list for struct
                    with only anonymous struct/union members
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major

Same error as issue 21961, but this time the parser misses that there are fields which have been added to the struct.
---
struct outer
{
 struct
   {
     int nested;
   };
};
---

This would suggest the type is not being constructed in the same way that D anon struct/union types are.
