I don't have a W10 ver 1511 yet, but even then it's hard to see that
this may be Cygwin's fault. It worked so far with all versions of
Windows since XP 64, including the pre-1511 W10.
There must be a bug in the new CMD somewhere. But, anyway, I'll look
into it when I finally managed to update my W10 test machine.
