[Inkscape-user] Compiling on Win32

I followed the directions from JonY to compile the SVN on Win32 (I know I don't really need to as the new win builds are perfect but I enjoy the challenge) and I keep hitting the same problem. When I run 'g++ buildtool.cpp -o btool' I get a string of errors starting with -

buildtool.cpp:53:18: error: string: No such file or directory buildtool.cpp:53:18: error: string: No such file or directory buildtool.cpp:53:18: error: string: No such file or directory
