you should NOT need IN_RING0, this can only cause problems. 
VBOX_WITH_XPCOM should be automatically detected based on RT_OS_...

Also I wonder why you do it this way, normally these defines are 
specified in the compiler command line, see below.

These are compile time assertions which fail... I guess it's the first 
two AssertCompile ones which check the size of the Utf16 char type to be 
consistent. It means you forgot to make sure that you're compiling the 
code with -fshort-wchar. Again see the sample makefile, it contains all 
these details.

In other words, make sure that you compile with
plus whatever options you need for the rest of your code.
