The commands you show work correctly with older version of the software.
Specifically, I've tried this:
mcrypt-2.6.7-1.tar.bz2
libmcrypt4-2.5.8-1.tar.bz2
libmcrypt-2.5.8-1.tar.bz2
Although on Ubuntu 12.04 LTS latest versions of mcrypt and libmcrypts
work with these two commands.

It looks like this could be a Cygwin issue then.
As alternatives, it seems that ccrypt and openssl work just fine:
$ echo "abcde" | ccrypt -u -K xyz | ccrypt -d -u -K xyz
abcde
$ echo "abcde" | openssl des -k xyz | openssl des -d -k xyz
abcde
$
crypt, OTOH, seems also to be broken, if I'm using it correctly (no
man page or --help option):
$ echo "abcde" | crypt xyz | crypt xyz
abA7GTEBsFqY6
$
If these utilities are broken, maybe they should be fixed or
removed from the distribution.
