[Cuis-dev] Real Joy on Linux was ( Updates to VectorGraphics and precompiled MacVM)

[David T. Lewis]

Hi Juan,

Yes. I think that the only necessary update for VMMaker will be something
like the attached, which moves the sqConfig.h include in the generated
code for all plugins. I tried this change on classic VMMaker for interpreter
VM, and everything worked as before. The generated code for VectorEnginePlugin
will work on opensmalltalk-vm (after the fix_include_order branch is
merged). This is probably the same thing that Gerald Klix did, and I
think it is the right solution.

Dave
