+ // notice that we unfortunately need all those overloads because we use
+ // the type of the date string to select the return value of the
+ // function: it's wchar_t if a wide string is passed for compatibility
+ // with the code doing "const wxChar *p = dt.ParseFormat(_T("..."))",
+ // but char* in all other cases for compatibility with ANSI build which
+ // allowed code like "const char *p = dt.ParseFormat("...")"
+ //
+ // so we need wchar_t overload and now passing s.c_str() as first
+ // argument is ambiguous because it's convertible to both wxString and
+ // wchar_t* and now it's passing char* which becomes ambiguous as it is
+ // convertible to both wxString and wxCStrData hence we need char*
+ // overload too
+ //
+ // and to make our life more miserable we also pay for having the
+ // optional dateDef parameter: as it's almost never used, we want to
+ // allow people to omit it when specifying the end iterator output
+ // parameter but we still have to allow specifying dateDef too, so we
+ // need another overload for this
+ //
+ // FIXME: all this mess could be avoided by using some class similar to
+ // wxFormatString, i.e. remembering string [pointer] of any type
+ // and convertible to either char* or wchar_t* as wxCStrData and
+ // having only 1 (or 2, because of the last paragraph above)
+ // overload taking it, see #9560
