This has been reported as far back as 2002 [1], and there were a few
reports in 2004 [2] and 2005 [3].  Corinna claimed [4] that this was
fixed, but I can still easily reproduce this with both 1.5.20 and the
latest snapshot (20060718), using the latest openssh/openssl.
STC (from a console bash):

$ uname -svr
CYGWIN_NT-5.1 1.5.21s(0.156/4/2) 20060718 11:35:58
$ echo $CYGWIN
check_case:strict ntsec notitle binmode nosmbntsec notty
$ DISPLAY=127.0.0.1:0.0 /bin/ssh -X user AT unixhost
[user AT unixhost] <Ctrl-C>Killed by signal 2.
$

I will try to investigate this as time permits, but if someone better
versed in Cygwin signal handling cares to take a look, I won't complain.
As Rob said, adding "tty" to $CYGWIN is a workaround.
