Thanks, that makes a lot more sense now.

Now, when I try to build the networking tests I seem to be missing some
headers.
For example, building ping_test.c I get:

In file included from /eCosBuild/Test_install/include/network.h:40,
                 from ping_test.c:34:

Any ideas where I can get them?

Thanks,
