The core reason is that the Binary Interface specific the name-mangling 
in C++ is different between gcc and MSVC, on top of that the 
documentation in the MSVC case is "sparse".
Then you will end up with two runtimes for C++, and to run MSVC and 
GCC(g++) in parallel requires a very consistent way of doing things 
since among all other things ther will be two different heaps...
