To clarify the question a snippet from the source, that shows that
__do_global_dtors is only implementet when compilining with gcc <=2, and
decared extern when compilling with gcc >= 3:

#if (__GNUC__ <= 2)

#ifndef CTORS_SECTION_ASM_OP
#define CTORS_SECTION_ASM_OP    ".section\t.ctors,\"aw\""
#endif
#ifndef DTORS_SECTION_ASM_OP
#define DTORS_SECTION_ASM_OP    ".section\t.dtors,\"aw\""
#endif

#else /* ! (__GNUC__ > 3) */

extern void __do_global_ctors_aux(void);
#define __do_global_ctors __do_global_ctors_aux
extern void __do_global_dtors_aux(void);
#define __do_global_dtors __do_global_dtors_aux

#endif /* __GNUC__ > 3 */

...
...

#if (__GNUC__ <= 2)
extern int atexit( func_ptr function );

static func_ptr __DTOR_LIST__[];
static void
__do_global_dtors(void)
{
        static func_ptr *p = __DTOR_LIST__ + 1;
...
...
}

extern func_ptr __CTOR_LIST__[];
static void
__do_global_ctors(void)
{
...
...
}

#endif /* ! (__GNUC__ > 3) */
