Really? gdb-6.4 works on a really simple program:
  $ cat a.c
#include <stdio.h>
#include <stdlib.h>

int
main (void) {
  puts ("hello world");
  exit (1);
}
  $ gcc-3.4.3 -g a.c
  $ gdb-6.4 a.out

5       main (void) {
6         puts ("hello world");
7         exit (1);
8       }
(gdb) continue
Continuing.
hello world

Program exited with code 01.
(gdb) quit

Of course, this doesn't mean gdb works "well" as this is a trivial
example.
