Undefined Symbol: ModuleInfo when Linking DLL Test Program

[GeorgeToth]

I am sure this a stupid mistake on my part.... I create a DLL Test0.dll from 
the following
file (Test0.d):
=========
module Test0;

import std.stdio;

class Test0
{
export
 {
  int Test0( string ID0 )
    {
      printf("<Test0: ID={%s}> ",ID0.ptr);
      return ID0.length+5;
    }
 }  // export end
}

export Test0 instTest0() { return new Test0(); }
=========
Lib listing shows the following symbols:
Publics by name         module
_D5Test05Test05Test0MFAyaZi      _D5Test05Test05Test0MFAyaZi
_D5Test09instTest0FZC5Test05Test0 _D5Test09instTest0FZC5Test05Test0


Publics by module
_D5Test05Test05Test0MFAyaZi
        _D5Test05Test05Test0MFAyaZi

_D5Test09instTest0FZC5Test05Test0
        _D5Test09instTest0FZC5Test05Test0

=======
It seems everything exported properly.  I wrote the following Test Harness 
Test0h.d:
============
module Test0h;

import Test0;
import std.stdio;

int main()
{
        Test0 t0 = instTest0();

        puts("Starting main()");
        auto tret = t0.Test0("Harness Test0h");
        printf("T0 Ret=%d\n",tret);
        puts("Ending main()");
        return 0;
}
=========
with the following Import Definition file:
=========
module Test0;

import std.stdio;

class Test0
{
    int Test0(string ID0);
}

Test0 instTest0();
=========
Watching the compile in verbose mode I get the following with the concluding 
error:

=========
I can't get the Test0 to be recognized.  If I add it to the compile then of 
course it works,
and runs properly, but that defeats the purpose of the DLL.  Can someone point 
out my error?
