Yes.  (At least in the case of the 'tty' option.  That must be set
before bash starts.)

Okay -- confirmed.  (Now I also know what "broken" means -- it means
only that typed characters are not echoed to the screen).  However, this
"problem" occurs only when you do something naughty:  set CYGWIN=tty
after starting bash, and only if running bash in a dos box (does not
happen when running bash in an rxvt window).
