I was asked something in a *compilation* window

[Dan Jacobson]

What happens when we do M-x compile and something asks us a question
right there in the compile window?  No, echo y > /dev/pts/4 doesn't
work.  Maybe one has to echo to /proc/... . Anyway, the user can't
talk back thru the terminal glass... there should be a way made
possible just in case.  I mean otherwise all you can do is start the
job over [not always an option].

No, I didn't expect it to ask me but it is, now what?
