Buid fails on OSX 10.3.9

["Florian G. Pflug" <fgp(at)phlo(dot)org>]

Hi

The build fails since yesterday on OSX 10.3.9, using wx-2.7.0
This is the error message:
dlg/dlgIndex.cpp:42: error: invalid static_cast from type `<unknown type>' to
   type `void (wxEvtHandler::*)(wxListEvent&)'
dlg/dlgIndex.cpp:43: error: invalid static_cast from type `<unknown type>' to
   type `void (wxEvtHandler::*)(wxCommandEvent&)'

I didn't have the time yet to look into this - maybe someone has here has an
idea about what gcc is unhappy about...

greetings, Florian Pflug
