I would think you will find the alien plugin source is under

But as far as I can see the only author is Eliot, with changes by me to fix a few things and expand a bit on the PowerPC support.
Further to this
The class comment says:
"This plugin implements the Newsqueak foreign-function interface, a small elaboration on the Strongtalk FFI.
Call-outs are performed by a small number of primitives, one each for the four different kinds of return linkage on x86. The primitives are var-args. Each primitive has a signature something like:"

Any news on this?
John,
Can you offer any guidance on this?
I have not looked at this in any detail, but it look like the Alien-VMMaker-Support package could potentially be merged into VMMaker (assuming MIT license for those changes), and the remainder of the Alien on SqueakSource should be maintained as a separate package, as is already the case.
I have not tried building the Alien support, but I appears that for 32-bit Intel platforms it would be a matter of building the plugin from sources in Alien-VMMaker-Plugins. The remainder would be image changes to be loaded from the remaining packages in Alien from your SqueakSource project.
Is that correct?
Dave
