C++, type lookup in function with parameter of same name

Describe the bug
When the same name is used for a function parameter as for a type used in the same declaration,
then the type sometimes gets linked to the wrong thing.

To Reproduce
Steps to reproduce the behavior:

.. cpp:struct:: abc::something

	.. cpp:var:: int x  

.. cpp:struct:: abc::otherthing

	.. cpp:function:: otherthing(const something &something)

		The ``something`` type gets linked to the ``something`` variable,
		instead of the ``something`` class.

Expected behavior
When making cross-reference in function declarations the lookup should take the relative position inside the declaration into account.

Environment info
Any Sphinx version.
