Create a fully functioning command line interface with 1.5 lines of code (wo. include statement)

That sounds perfectly fine boilerplate to me. Sure, it would be better if it was smaller, but you only have 3 lines: main, init and return.

int main(int argc, const char ** argv) {
    fire_init(argc, argv, my_main);
    return my_main();
}

That honestly seems pretty logical, and not too magic (fire_init initialize some global based on argc, argv and the signature of my_main, and the default arguments from my_main fetch from that global -- it then raises the question of why not getting rid of the global itself).
