Just noticed a minor thing:

  -  push_target (ptrace_ops_hack);
  +  int pid = fork_inferior (exec_file, allargs, env, inf_ptrace_me, NULL,
  +                          NULL, NULL);
  +
  +  push_target (ops);

Mark mentioned that he would prefer to have:

   int pid;

   pid = fork_inferior (...)

I have been hoping to contribute a couple of things, which include
thread support on Tru64. Hopefully I will get to that soon, and if
I beat to checking my patch in, you'll have to fix one extra file
(just teasing you :-).
