Correct test case:

g1.c:
int f() { printf("strong"); return 82; }
int g() { printf("strong"); return 83; }

g2.c:
#include <stdio.h>
static int weak_f() { return 42; }
static int weak_g() { return 43; }
typeof(weak_f) f __attribute__((__weak__, __alias__("weak_f")));
typeof(weak_g) g __attribute__((__weak__, __alias__("weak_g")));
int main() { printf("%d/%d\n", f(), g()); }

g3.c:
static int default_f() { return 42; }
static int default_g() { return 43; }
static typeof(default_f) weak_f __attribute__((__weakref__("f")));
static typeof(default_g) weak_g __attribute__((__weakref__("g")));
int main() { printf("%d/%d\n", (weak_f?:default_f)(), (weak_g?:default_g)()); }
