cppclean suggests forward declaring something which is an enum

[jwpeterson]

But this isn't allowed by the C++03 standard. The following simple test code (two files) demonstrates the issue:

myenum.h:

enum MyEnum {FOO, BAR, BAZ};

cppclean_test4.h:

// Header file where enum MyEnum is defined.
#include "myenum.h"

class A
{
  // f takes a reference to MyEnum, but as an enum it can't be forward declared.
  void f(MyEnum & bar);
};

cppclean prints:

cppclean_test4.h:2: 'myenum.h' does not need to be #included; use a forward declaration instead

Thanks for the report. This is fixed now :)
