[Vm-dev] Running Alien on Windows

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.
