Let me clrify again that I don't think that this is the feature optionally
supported by compilers. By now almost all cvompilers I know supports RTTI
one way or another.
Unfortunately from my expirience RTTI implementations usually have
non-negligeble runtime overhead (in both speed and size). Be aware that if
even one class in progrma is using std::type_info, I am forcing to turn on
RTTI that affects *all* classes.

I could not turn of RTTI once typeinfo is included. I will get link errors.
