gnutls and Emacs on Windows

[Gary <help-gnu-emacs@garydjones.name>]

When using jabberEl in my normal emacs (Cygwin nox build) I see the
following when I (successfully) connect:
,----
| Opening TLS connection to `talk.google.com'...
| Opening TLS connection with `gnutls-cli -p 5223 talk.google.com'...done
| Opening TLS connection to `talk.google.com'...done
`----

but the same config in the Windows build (see sig) produces:
,----
| Opening TLS connection to `talk.google.com'...
| Opening TLS connection with `gnutls-cli -p 5223 talk.google.com'...failed
| Opening TLS connection with `gnutls-cli -p 5223 talk.google.com --protocols ssl3'...failed
| Opening TLS connection with `openssl s_client -connect talk.google.com:5223 -no_ssl2 -ign_eof'...failed
| Opening TLS connection to `talk.google.com'...failed
`----

I suspect I need to install some other gnutls build or something like
that?

Can I use the already installed Cygwin gnutls "stuff"? 

Is there an alternative to gnutls if none of that works (I think I can
use openssl, but haven't even looked at how that might work with the
Windows build yet).

Has anyone come up against gnutls problems using the Windows binary and
can point me in the right direction?
