IIRC, it was partially requests from users and partially the
realization that most users want platform independent syntax but
platform dependent semantics.

If you would like your example to append a slash, use the (relatively
new) path concatenation operator +=

    p += "/c";

If you would rather continue to use operator /= then change the output to

    cout << p.generic_string();
