[Bug c++/21347] New: spurious warning with -Wctor-dtor-privacy

["bh at techhouse dot brown dot edu" <gcc-bugzilla@gcc.gnu.org>]

cat > foo.cpp << EOF
class A {
    public:
    int x;
    int getX() { return x; } // comment out to avoid warning
};

int foo() {
    A a; // accepted: clearly the ctor is not private
    return a.x;
}
EOF
g++ -c -Wctor-dtor-privacy foo.cpp
foo.cpp:1: warning: 'class A' only defines private constructors and has no friends

This occurs in 4.0.0 and is a regression from 3.3.5 and 3.4.3.
