xterm does still send ^H, but I agree both xterm and its termcap entry
ought to be changed to match the new Cygwin 1.7 default and the Linux
world. I should have a look at how to do that.

Have you come across an application that stumbles over this? All the
one's I've tried seemed to go by the stty setting rather than the
termcap entry anyway.

The workaround is to stick the following somewhere in your startup files:

echo $'\e[?67h'
stty erase '^H'

The first line emits a 'DECBKM' sequence, which switches mintty back
to ^H mode, and the second line changes the pty setting accordingly.
