Although I had some problems with optimizations and BFS, I doubt that 
this is a general problem (when using a current compiler).

I think so, too, that's why we don't allow do use them. We also don't 
make use of RTTI; we don't need a C++ runtime at all.

That's simply not true - the only overhead that could be caused by C++ 
is a slightly larger memory usage because one tend to encapsulate more 
data. But that's really not much if measurable at all.
Just have a look at how I used C++ in BFS - it makes the code a lot 
better, easier to read and removes many critical pitfalls (like 
cleaning up in case of an error - I tend to create those objects on the 
stack, so C++ will always clean up automatically when I make a simple 
"return").
Also, C++ has better type safety.

Adios...
