You do don't need type conversion here:

   Sleep_T : constant Duration := 0.0001; -- This is OK

I remotely remember a discussion about this compiler bug  It was discussed
in comp.lang.ada some time ago. I also remember that some people mentioned
tasking problems also circumvented by an initial delay. Which BTW can be
just 0.0;

My explanation is that GNAT RTL is improperly elaborated under Windows.
Fortunately, a delay at the program beginning wakes it up.
