            Bug ID: 23905
           Summary: incomplete type diagnostic
           Product: clang
           Version: 3.6
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend

Hi,
For the following case, clang gives error for struct but not for enum:

extern struct foo s;
extern enum bar b;

int main()
{
  (void) s;
  (void) b;
}

f1.c:9:10: error: incomplete type 'struct foo' where a complete type is
required
  (void) s;
         ^
f1.c:1:8: note: forward declaration of 'struct foo'
struct foo;
       ^
1 error generated.

Is this possibly a bug ?

clang --version:
Ubuntu clang version 3.6.0-2ubuntu1 (tags/RELEASE_360/final) (based on LLVM
3.6.0)
Target: x86_64-pc-linux-gnu
Thread model: posix

Thank you,
Prathamesh
