[Bug c++/50518] New: repeated c++11 opaque enum declarations are invalid

             Bug #: 50518
           Summary: repeated c++11 opaque enum declarations are invalid
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: fabien@gcc.gnu.org


The below example should not compile:

struct B
{
 enum E: int;
 enum E: int;
};

Repeating opaque-enum-declarations at class scope is invalid under 9.2/1:

--
A member shall not be declared twice in the member-specification, except that a
nested class or member class template can be declared and then later defined,
and except that an enumeration can be introduced with an
opaque-enum-declaration and later redeclared with an enum-specifier.
--

However,

struct A
{
 enum E: int;
 enum E: int { e1 };
};

is OK.

No, sorry, I'll try to work on it before the end of stage 3.
