If you mean by non-conforming "non-conforming to the not existing yet new C++ standard, so far known as C++0x", the answer is yes. > If so, is there some compiler flag to switch to a conforming > (non-ref-counting) std::string implementation? Nope. > If I understand well, the Versatile String, __versa_string from > <ext/vstring.h> provides such an implementation, right?

And of course that code is just a starting point. Before advertising is a "conforming" (in the sense above) implementation has to be reviewed, some optimizations added, etc...
