Unfortunately as it stands it will only work on Windows.

The major problem is the "foo" structure on other platforms that's
used to hold most of the interpreter's variables.

That's why the accessor methods used to call addressOf: rather than
just being "self cCode: '&foo->activeContext'" which is what I
originally did until Andreas tried to do a quick Windows port. He
created addressOf: to provide a platform neutral way of getting the
address of an interpreter structure.

#returnPrefixFromVariable: will return the right form for a variable
on any platform. Unfortunately, you can't dereference foo in another
structure's initialiser.

Andreas created #generateAddressOf:on:indent: to translate
the sender #addressOf: into the appropriate C expression.


I'm not sure about your change to Win32VMMaker>>sourceDirectory.
If I add that to Exupery's VMMaker what will it do to people with
existing Windows build environments?


I like the changes to Exupery itself, it makes the names much more
consistant between the image and the VM but until it will run on
all plaforms I can not accept it.
