wxWidgets/include/wx/filefn.h
Robert Roebling 92980e9076 Changed wxStat, wxAccess and wxOpen to no longer
being just a define so that the signature is
    using wxChar under Unicode under Unix just as
    it does under Unicode under Mac. This required
    some modification in various places, but should
    make debugging a little easier, among others.
