It already does, see below...

Well, currently it does make a difference. Simple example: CreateFile(). One 
of the parameters is actually documented at LPCTSTR, which is a TCHAR string. 
That means that under CE, CreateFile(), which is actually a macro, resolves 
to CreateFileW and the existing code that passes a char-string doesn't work.

I'll take a look, I actually don't know.

VS2005 works really good with CE5 and later. My problem here is that I can't 
provide a projectfile that suits everyone, because different devices have 
different SDKs and each configuration/SDK/CPU is another entry in that file. 
Further, the SDKs or devices differ in what they support, the platform CE as 
such doesn't exist.
