In order to simulate a compiler's preprocessor the compiler must be 
installed so that GCC-XML can find it's system headers.  If you install 
cygwin then you can build GCC-XML from source under cygwin and then it 
will have no problem simulating cygwin's g++.  I've never tried it but 
you might be able to get the windows version of GCC-XML to simulate g++ 
if you have the mingw g++ version installed.  Use gccxml --print to see 
the flags settings.  If you override the GCCXML_EXECUTABLE and 
GCCXML_FLAGS settings then you can simulate any compiler you want.
