related functions rather than wx functions which might do the same thing. This
is because I did not want to become very dependent on wxWidgets at such a low
level as this, in case someday this code needs to be used on kde or whatever.
Mingw and unix, linux, & osx will all have these posix functions.
MS Visual Studio may need the posix compatible opendir() functions brought in

wx has these but they are based on wxString which can be wchar_t based and wx should
