wxWidgets30 libraries oddities

Hi there,

When I build wxWidgets30, I get these, e.g. in libwx_osx_cocoau_html:

Air > nm /opt/local/lib/libwx_osx_cocoau_html-2.9.dylib | c++filt | grep SetHTMLWindowTitle
000000000004284a T wxHtmlWindow::SetHTMLWindowTitle(wxString const&)
0000000000063250 T wxHtmlListBox::SetHTMLWindowTitle(wxString const&)
000000000004285c T non-virtual thunk to wxHtmlWindow::SetHTMLWindowTitle(wxString const&)
0000000000063256 T non-virtual thunk to wxHtmlListBox::SetHTMLWindowTitle(wxString const&)

Those “non-virtual thunks” then give rise to errors when one tries to link against the missing functions, e.g.:

  "non-virtual thunk to wxHtmlWindow::SetHTMLWindowTitle(wxString const&)", referenced from:
      vtable for CACTIVE_Description in active_description.o
      vtable for CACTIVE_HTMLExtraInfo in active_HTMLExtraInfo.o

Since I am totally ignorant of the arcanes of C++, can someone tell me if this a bug or an expected behavior under appropriate conditions?
