[Bug c++/39730] New: C++ incomplete type error can be misleading

For this example:

# include <istream>
# include <istream>

using namespace std;

ifstream  x;
ifstream  y();

int main(int argc, char** argv) {
  return 0;
}

current mainline g++ says:

foo.cc:6: error: aggregate ‘std::ifstream x’ has incomplete type and cannot be
defined

This is accurate but confusing for the uninitiated.  How about something like

foo.cc:6: error: ‘std::ifstream’ was declared but not defined

This is even more confusing to me.  As incomplete types are understood easier
than just being declared and not defined.
