    Fix Cygwin compilation after target_ops C++ conversion.
    
    After f6ac5f3d "Convert struct target_ops to C++", we need to explicitly use
    the global namespace when calling ::close() from windows_nat_target methods,
    as that object has a close() method.

    	* windows-nat.c (windows_nat_target::create_inferior): Update to
    	call close() in global namespace.
