reference cpp constructor

[Robert Cohn]

I want to reference a specific overload of a cpp constructor. The first reference fails, but 2 & 3 succeed. Adding a void to a constructor reference seems wrong. What is the right way?

.. cpp:class:: Y

  .. cpp:function:: Y(int a)

  .. cpp:function:: Y(float)

  .. cpp:function:: void X(double)

:cpp:func:`Y::Y(int)`

:cpp:func:`void Y::Y(int)`

:cpp:func:`void Y::Y(float)`
