Hi Fredrik

Would you consider contributing your code changes back to the uC/IP
project?  I know there has not been much activity in the last years but
it is still regularaly downloaded so many are still finding it useful.

I was considering using this stack on the Atmel AVR uControllers with an
OS called AvrX and the size of the above modules look very good to me.
