>Description:
GCC fails to compile a valid typedef of an anonymous struct when the name of the typedef is identical to a namespace in an outer scope.

See the code below to reproduce the problem. The line resulting in the error has been marked with "// conflict with A namespace!!!".
>How-To-Repeat:
Here is some code that illustrates the problem:

namespace A {};

namespace OtherNamespace {

  typedef struct {
    int member;
  } A; // conflict with A namespace!!!

}; // end of namespace

int main() {
  return 0;
}
