Dont know what should be the next steps to get Alien into the Win32-VM code base. Maybe Andreas could tell you more.
As a workaround you could use the source provided by Marco to build your own unofficial VM - however you would have to reintegrate anytime Andreas makes a new release...

May be I'm in a good mood but I think that andreas will do it when he got time. I know what is losing time on a lot of tiny boring stuff that must be done.

Hi Torsten -
Thanks for cc-ing vm-dev; I wouldn't have seen this post otherwise. I've actually looked at the code since and there's some good news here: It appears that there's no actual modification of the Windows support code necessary to use Alien. The only difference is a flag in sqWin32Window.c which for all intents and purposes appears to be completely unused.
That leaves the question of how to deal with the patches to the VMMaker code base. As you know, my "official" VMs are always built from the "official" sources (i.e., the latest VMMaker package on http://www.squeaksource.com/VMMaker.html) and if you'd like to help getting Alien support into the standard builds we should figure out how to integrate these patches.
Perhaps David and/or Eliot can help? From my perspective this issue doesn't really belong with the Windows VM but rather with the VMMaker package. I just build whatever is in there, so if Alien support is in, then I'll build it together with everything else.
Cheers, - Andreas

Yes, I'll be glad to help. I'll look at it as soon as possible (probably not until this weekend though).

I added Alien functions to VMMaker on SqueakSource:
Name: VMMaker-dtl.170 Author: dtl Time: 25 April 2010, 3:21:08.401 pm Ancestors: VMMaker-dtl.169
VMMaker 4.1.0
Include support for Alien FFI in the interpreter. This adds the contents of package Alien-VMMaker-Support from the Alien project on SqueakSource. The Alien plugin has not been included, and continues to be maintained in package Alien-VMMaker-Plugins on SqS/Alien.
These additions are copyright and licensed as follows (reference SqS/Alien):
Copyright 2008 Cadence Design Systems, Inc. Licensed under the Apache License, Version 2.0 (the ''License''); you may not use this file except in compliance with the License. You may obtain a copy of the License at http://www.apache.org/licenses/LICENSE-2.0 Aug 27th, 2009
I also updated platforms/Cross/vm/sqVirtualMachine.[ch] with the Alien functions. This bumps the VM_PROXY_MINOR version to 8, and requires that VMs be generated with VMMaker-dtl.170 (or that you load the equivalent from the the Alien project on SqueakSource).
I updated the configuration map so that "VMMaker updateFromServer" will now pull in the Alien plugin. A similar update will be needed for ConfigurationOfVMMaker for Pharo.
Note that this adds Apache licensed code to VMMaker. If there are any concerns about this, please speak up.
