there does not seem to be any reference to this function anywhere in the
gdbserver code that i have. maybe  i have a very old version but the
source has not changed for the last 12 months or so for the thread-db.c
file. just checked that on cvs. the error seems to come in
thread_db_init() and precisely when it tries to find the new threads. 


could someone explain why this code sits inside such a function . isnt
this strange??
static void
linux_look_up_symbols (void)
{
#ifdef USE_THREAD_DB
  if (using_threads)
    return;

  using_threads = thread_db_init ();
#endif
}
