What append if my library staticaly call a function foo () that is used in my 
code by the main function.

/*
 Main.c
*/

static void bar () {}
void foo () { bar (); }

int main (int argc, char argv[])
{
  libcall ();
  foo ();
}

/*
 Mylib.c
*/

void libcall () { foo (); }

I think that you couldn't know anything about the librairie, and you couldn't 
detect if your program use this thing or not, because it came from the 
outside...
