I could imagine having each file's _initialize function start with:

void
_initialize_foo (void)
{
  static initialized;

  if (initialized)
    return;
  initialized = 1;

  ...
}

A sed script could get the job done.  Then, they could call each other
with wild abandon.  For extra points, you could do:

void
_initialize_foo (void)
{
  static int initialized;

  assert (initialized != 1);
  if (initialized)
    return;
  initialized = 1;

  ...

  initialized = 2;
}

So you'd catch circular dependencies.
