The rtermios default setting will need to change accordingly,
either by changing the definition of CERASE in include/sys/termios.h:

-#define CERASE CTRL('H')
+#define CERASE CDEL

Or by changing the initialisation in fhandler_termios.c:

-      tc->ti.c_cc[VERASE]      = CERASE;
+      tc->ti.c_cc[VERASE]      = CDEL;

The cygwin section in /etc/termcap doesn't have a kb entry, so luckily
no change needed there.

terminfo has an entry for backspace though:

$ tput -T cygwin kbs | cat -v
^H

So this has to to change as well:

+++ terminfo.src        2009-05-30 07:50:44.893933600 +0100

-       kbs=^H, kcub1=\E[D, kcud1=\E[B, kcuf1=\E[C, kcuu1=\E[A,
+       kbs=^?, kcub1=\E[D, kcud1=\E[B, kcuf1=\E[C, kcuu1=\E[A,

And then there are rxvt and xterm and their termcap and terminfo
entries as well ...
