[ECOS] fatal error when building ecos with lwip

[Robert Brusa]

Hi
I added the packages CYGPKG_NET_LWIP v3_0 and CYGPKG_IO_ETH_DRIVERS v3_0  
to my (proven) template, configured tcp and started the build. But hellas  
- it runs on a severe problem:

Does anybody know how to fix this problem? And what's about these  
warnings? Thanks for help.
