* remote.c (remote_notice_new_inferior): Use ptid_is_pid. Check
if the thread's ptid without a thread id field is in the list before calling thread_change_ptid. (extended_remote_attach_1): In non-stop mode, do not rely on querying the current thread, instead, query the thread list, and select the first thread of the process. * gdbthread.h (first_thread_of_process): Declare. * thread.c (first_thread_of_process): Define.
