Yes, that's exactly what I meant to imply.  Without further description of
your problem, this is about as much advice as anyone can suggest.  FYI,
the terminfo database has changed a few times, and I'm not at all certain
that the 'kbs' value stayed intact.  On my system, 'tput kbs' prints ASCII
BS.

I still think 'stty' is what you want.  Another place to look is the shell
initialization files (e.g., the default /etc/profile has a bash-specific
section that issues 'stty erase ^?' -- has that section become
bash-specific recently?).

Alternatively, look at the CVS history of fhandler_console.cc in
winsup/cygwin.  That should tell you if anything changed WRT the character
produced by BackSpace.
HTH,
