Add include guards in all your *.h or *.hh header files (unless you have specific reasons to not do that).

To understand what is happening, try to get the preprocessed form of your source code. With GCC, it is something like g++ -Wall -C -E yourcode.cc > yourcode.i (I have no idea on how Microsoft compilers do that). You can also ask which files are included, with GCC as g++ -Wall -H -c yourcode.cc
