I don't know of any reason why it wouldn't be OK to pass
a std::string across a dll boundary, as long as the
string class's object layout matches. But why not just
pass a 'char const*'? Then you could call your extern "C"
functions from a C program, and the stl allocator doesn't
come into play outside the dll.
