You might be misunderstanding part of the Makefile.  The comment that says 
"#To compile for linux: make ARCH=linux" means "if you want to compile for 
linux, make the following line in the Makefile read "ARCH=linux" rather 
than "ARCH=unix" or "ARCH=cygwin""  I don't think it's an option you can 
just specify on the command line.

Just typing "make" is the right way to build it, I think.

It is in the Makefile distributed.

Looks like you're missing the "depend" command.  You'll need to install 
that or make sure it's on your PATH before you can make anything.

Again I don't think you need the "arch = unix" on the command line.

That's odd - the Makefiles look fine to me.  What OS are you building on, 
and what compiler and version of make are you using?  Are you able to 
build anything, such as non-lwIP things?

Hope that helps,
