Hello,
you would need to check out the "contrib" module from CVS as well.
This contains all the architecture ports, some network interface drivers
and applications.
The Unix port has a makefile, you only need to specify the correct
path of the lwIP sources and it should compile lwIP as a library.
This was tested against 0.6.x but should work against 0.7.0. Report
any problems here please.
I recon I should make an archive out of that one as well... Done!

Leon Woestenberg.
