Great!

Yes, that was it.

The standard way would be to add all lwIP files to a library which you can then 
add to your guild system. For small projects, adding all lwIP files will be as 
good.

However, including all files in one big C file might lead to the problems seen 
here. In general, in C it might also conflict with multiple static variables 
having the same name in different files, but I don't know if we have that in 
lwIP.

Also, I think the way lwIP redefines the socket functions can lead to problems, 
so we might consider changing it...
