[GCC-XML]Why does gccxml.exe demand MSVC on Windows?

The zipfile is a binary for the windows build of GCC-XML, which does not
understand cygwin paths.  In order to simulate g++ in cygwin, you need a
cygwin build of GCC-XML.  Download the source tarball and build it in
cygwin.  You'll need to install the CMake 1.6.x package from the cygwin
installer.


tar xvzf gccxml-0.4.1.tar.gz
mkdir gccxml-0.4.1-build
cd gccxml-0.4.1-build
cmake ../gccxml-0.4.1
make
make install

Then copy the gccxml_cc1plus exectuable you already have into
/usr/local/bin next to gccxml.exe.  You should then be able to run gccxml
from the cygwin prompt.
