Fix possible Cygwin build problem

I noticed that nat/windows-nat.c checks __USEWIDE, but nothing sets it
there -- I forgot to copy over the definition when making this file.
This patch tries to fix the problem.  I don't have a Cygwin setup, so
I don't know whether this is sufficient, but it's probably necessary.
