For anyone who's been playing with this, I just posted another new
revision of Alien that fixes the platform sizes to match C platform
sizes. Not sure what I was thinking in the first go-around. Anyhow, if
you load Alien-Core-kdt.58 in Pharo, you'll need to re-initialize Alien:
Alien initialize
In other news, I've got CairoGraphics mostly working in GemStone
(2.3.1) now too, running on top of an "Alien Lite" that provides
support for the types of function calls I need to make. If anyone is
interested in this, email me directly and I'll send you the code once
I've worked out the remaining major bugs.
