In the GPL case, it protects /modified/ code copies.

The example I brought, was written from scratch, it was therefore not a
"modified copy".

My example

#include <log.h>
int main(void) { zlog_rotate(); return 0; }

is not an adaption of any GPL code. It is fully written by my
own. Therefore, I don't need to respect the GPL to distribute it. The
same is true for the FRR code as far as I have seen it.

Otherwise you must point to a certain code file and prove that it
contains code which is a modified copy of an GPLed file. Which you not
did yet.
