[cfe-dev] Error Parsing Incomplete Enum Types

[Uri Mann]

I'm running into an error parsing the source:
// Enum.cpp
namespace ns {
    typedef enum _E E;
    typedef struct _S S;
}
namespace ns {
    typedef enum _E E;
    typedef struct _S S;
}
// End Enum.cpp

CLang output:
enum.cpp(6,20) :  error: typedef redefinition with different types ('enum _E' vs 'enum _E')
    typedef enum _E E;
                    ^
enum.cpp(2,20) :  note: previous definition is here
    typedef enum _E E;
                    ^

I'm not a C++ "lawyer" so I'm not sure if this is a CLang issue, or a construct forbidden by the C++ standard? If this is in the standard, why does the same not apply to struct?

Thanks in advance.
