[Bug c++/27078] New: Duplicate error message for ambiguous enum

[ian at airs dot com]

This C++ file:

enum E1 { V };
namespace { enum E2 { V }; }
int foo() { return static_cast<int>(V); }

when compiled with current mainline produces a doubled error message:

foo.cc: In function ‘int foo()’:
foo.cc:3: error: reference to ‘V’ is ambiguous
foo.cc:1: error: candidates are: E1 V
foo.cc:2: error:                 <unnamed>::E2 <unnamed>::V
foo.cc:3: error: reference to ‘V’ is ambiguous
foo.cc:1: error: candidates are: E1 V
foo.cc:2: error:                 <unnamed>::E2 <unnamed>::V

This duplication is pointless and confusing.
