I don't understand this.  What does Cygwin expect have to do with these
underlying OS calls?!?  They only work in a console window and they are
not to be suppsoed to be used by Cygwin executables since all the
underlying OS details are (more or less) hidden behind the TTY code.
Also, how are they supposed to work in a PTY which is constituted by
Named Pipes, not a console?  And expect certainly uses PTYs to perform
its pseudo-interactive stuff.
