Very strange linker error

[Mafi]

I'm trying to rebuild my projects with new dmd and after fixing some 
minor issues in my code I get the following:

Warning: As of Phobos 2.054, std.file.listDir has been scheduled for 
deprecation in August 2011. Please use std.file.dirEntries instead.

OPTLINK (R) for Win32  Release 8.00.12
Copyright (C) Digital Mars 1989-2010  All rights reserved.
http://www.digitalmars.com/ctg/optlink.html
obj\main.obj(main)  Offset 35B56H Record Type 00C3
  Error 1: Previous Definition Different : _D5mysdl5input8Joystick6__ctorM
--- errorlevel 1

So I went to http://www.digitalmars.com/d/2.0/abi.html (which I by the 
wy couldn't find on d-p-l.org) and it seems to be an incorrect mangling 
because there's no 'type' after M but maybe it's a special case for the 
constructor.

So looked for mysdl.input.Joystick.this(...). The struct (!) Joystick in 
input.d has two constructors:

     public this(SDL_Joystick* somePtr) {
         this.joyptr = somePtr;
     }

     public this(int index)
     in {
         assert(index >= 0);
         assert(index < Joystick.getCount());
     } body {
         this(SDL_JoystickOpen(index));
     }

No overlaping. So I went dumping all my object files and I found that 
dmd generated this strange sambol in input.obj twice. So it's not 
optlink's fault but dmd's!

I'd really like to solve this problem because otherwise this would be 
second release in a row that I can't use.
The worst thing is I don't even now any ugly workaround. :(
