Hi Janusz,
thanks for the patch! 

I planned to do something like that, but got swamped in other things.

I have only one question: why do we need the following:

-        to_internal(detail::make_vector(argv+1, argv+argc)))
+        to_internal(detail::make_vector<charT, charT**>(argv+1, argv+argc)))

Is it a bug in mingw's gcc?

As for converting from/to utf8 without wstring, I guess it's possible, but 
outside program_options. If wchar_t is not really supported, then:

1. You can't use wide parsers 
2. You can't pass wchar_t to program_options

So, essentially, it's only possible to use some external wchar_t -> utf-8 
converter and pass the resulting 8-bit string to program_options.

Thanks,
Volodya
