Perhaps it would be preferable to publish your PPP-related changes as a
patch for the time being and keep the CVS sources as close to the master
lwIP code as possible.

I can certainly test on an x86 PC target. I think Sergei Gavrikov has
also been experimenting with your port (probably on ARM). Are there any
volunteers to perform a basic sanity check of the eCos port on a
big-endian target?

Great.
