Indeed, this can be demonstrated with the following testcase:

===============================
struct A;

namespace N
{
    struct A;
}

using namespace N;

int A::i;
int A::i;

namespace N
{
    struct C;
    struct C {};
}

class D : N::C {};
===============================

With mainline I get the bogus error message:

PR19030.cc:10: error: 'A' has not been declared
PR19030.cc:11: error: 'A' has not been declared
PR19030.cc:11: error: redefinition of 'int i'
PR19030.cc:10: error: 'int i' previously declared here
PR19030.cc:16: error: conflicting declaration 'struct N::C'
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
PR19030.cc:15: error: 'struct N::C' has a previous declaration as 'struct N::C'
PR19030.cc:16: internal compiler error: tree check: expected class
'declaration', have 'exceptional' (error_mark) in pushtag, at
