How are you creating your window?    The  window, and any
depth/stencil/aux buffers associated with it, are not created by OpenGL,
but are part of the context created with the window via what ever method
you use to create the window.  So I repeat -- what method do you use to
create a window, and can you find a way to specify a stencil buffer at
that time?
