But the point is that setmode shouldn't be used on Cygwin

Why not?  What if the volume in question was mounted in text mode?
And even if it wasn't, wouldn't setmode be a no-op?

No, the symbol 'setmode' is no longer exported in 64bit Cygwin. That's what caused the build failure. And the code in pipe2.c that calls setmode should never actually get executed on Cygwin anyway because of this:

        int result = pipe2 (fd, flags);
        if (!(result < 0 && errno == ENOSYS))
          {
            have_pipe2_really = 1;
            return result;
