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;
