cvs wxString changes.

[Gunnar Roth]

hello,
the wxstring changes in cvs again break my app.
the line:
        return wxGetApp().Prefs.bDisplayEmptyPlaylistColumnAsUnkown == 
true ? _( "<unknown>" ):wxEmptyString;
yields the error: error: operands to ?: have different types

i build mac,unicode

replacing wxEmptyString by wxT("") fixes the error of course. but i 
regarded usage of wxEmptyString to be more memory efficient.


but  when i recommended to change wxListCtrl 's signature (some years ago)
virtual wxListItemAttr *OnGetItemAttr(long item) const;
to
virtual const wxListItemAttr *OnGetItemAttr(long item) const; ( to not 
be forced to const cast internal member access)
it was said that would break to compile for too many users.

regards,
gunnar
