| * |
| * For newer ones, 'atexit' is actually embedded in the C |
| * runtime objects that are linked into the final ELF |

| * __cxa_atexit() in order to un-register any atexit() |
| * handler when a library is unloaded. |
| * |
| * This function must be global *and* hidden. Only the |
| * code inside the same ELF binary should be able to access it. |
