[Bug 12171] adding popupmenu to itself, then using finditem causes stack overflow

I have tried the WZebra 2.4.2 application and I find that the problem is not in
the finditem. The real difference with Windows is that the ModifyMenu function
fails when attempting to create a loop in the menu tree.
Since all examples shown are ignoring the return value of ModifyMenu() this is
not noticed.

I have submitted a test that show the behavior of WZebra. Another test shows
that on windows there is a limit of about 25 on the depth of the menu tree,
probably used in the tests for loops in the menu tree.
