I think we're misunderstanding each other, because that is exactly the 
solution I'm targetting. I'm aware that TCHAR is just a hack to ease 
transition between obsolete MS Windows versions and NT and later. However, 
current state is that Python uses CreateProcessA() and changing that is not 
always trivial.

Therefore, my first step in porting is also to remove the dependency on TCHAR, 
i.e. replace things like CreateProcess() with preferably CreateProcessW() or 
alternatively CreateProcessA(). Just #defining _UNICODE in the build already 
turns up around 50 places in pythoncore that need work. I'll send patches

Hopefully, yes, but I'm not going to make any claims which I'm not sure about. 
SCons is just convenient because the PythonCE project already uses it but I'm 
not adamant on that matter. The approach of Jack Jansen also sounds good, 
generating the projectfiles (which are XML, btw) from a Python script also 
sounds nice.
