I've been following this thred as I was having the same problem (although only with tunneling a port between two machines).  I solved it by replacing the host name with the ip address in the ssh command, ie:

ssh  -R 8888:<ip address of C>:22 username@<ip address of B> cat -

instead of

ssh  -R 8888:C:22 username B cat -

or whatever variation you think would be more successful.  This certainly doesn't make any sense to me, but with the hostnames in place, I was unable to connect and getting "channel 2: open failed: connect failed: Connection refused."  Hopefully you're having the same issue.
