Sorry; I guess I misinterpreted you to be saying that somehow you
accomplish the trick by using ptys, when I suppose you were just saying
that this program could provide a pty so that bash is running in a
proper terminal

(My cheap FIFO hack avoids allocating ptys, which should be fine for
running "make" through it, and in the case of FIFOs (but not a spawned
shell-cmd idea) should even work with bash and "exec >out 2>err"; but of
course won't work on anything that expects its output fds to be ttys, as
well as the inputs.)
