That's odd, you don't have a single visual that supports a stencil buffer. I'm fairly sure that OpenGL requires at least one, but seeing as you don't have any I'll send in a new patch.
There's no requirement that a GL implementation supports stencil buffers in any way (or accumulation buffers, or indexed-colour modes, or destination-alpha, or quad-buffers, or...), unless of course it advertises a visual with those features, which it is under no obligation to do.
