`config.h` has all the defines from autoconf, which may include things that switch behavior of other included headers (e.g. _GNU_SOURCE enabling prototypes for additional functions.) So, the first include in any `.c` file must be either `config.h` (with the appropriate guard) or `zebra.h` (which includes `config.h` first thing.)
