Also, doesn't give hassles with Windows File Protection under 2000+ (even
though that can be disabled).
As far as I can see, at the moment we just need a simple way to get 
development
going, and the development should be done in such a way that later on 
it'll be
easy to rearrange the code.
So we could use this approach and then if later we want to actually
replace user32.dll or do something like that we could.
Also, if we have a structure in place, even if it only translates a 
simple program
we can then bring in code from wine etc and see how easy it would be to 
merge it
in.
I've got a simple hello world done in the Win32 API which could be a 
first goal.
Then we could do enough to run notepad and solitaire...
