Considering that all the project's header files have inclusion guards,
there is, in fact, no real recursion to speak of, right?

https://en.wikipedia.org/wiki/Include_guard

#ifndef __LWIP_OPT_H__
#define __LWIP_OPT_H__
...
#endif /* __LWIP_OPT_H__ */

We could discuss why it is bad form to define a macro that starts
with two underscores, but that's another subject.
