old-cross-binutils/gdb/gdbserver/inferiors.c
Daniel Jacobowitz a1928bada5 * inferiors.c (change_inferior_id, add_thread, find_inferior_id):
Take unsigned long arguments for PIDs.
	* linux-low.c (add_process, linux_attach_lwp, linux_attach)
	(linux_thread_alive, linux_wait_for_event, kill_lwp, send_sigstop)
	(wait_for_sigstop, linux_resume_one_process)
	(regsets_fetch_inferior_registers, linux_send_signal)
	(linux_read_auxv): Likewise.  Update the types of variables holding
	PIDs.  Update format string specifiers.
	* linux-low.h (struct process_info, linux_attach_lwp): Likewise.
	* remote-utils.c (prepare_resume_reply): Likewise.
	* server.c (cont_thread, general_thread, step_thread)
	(thread_from_wait, old_thread_from_wait, signal_pid): Change type to
	unsigned long.
	(handle_query): Update format specifiers.
	(handle_v_cont, main): Use strtoul for thread IDs.
	* server.h (struct inferior_list_entry): Use unsigned long for ID.
	(add_thread, find_inferior_id, change_inferior_id, cont_thread)
	(general_thread, step_thread, thread_from_wait)
	(old_thread_from_wait): Update.
	* target.h (struct thread_resume): Use unsigned long for THREAD.
	(struct target_ops): Use unsigned long for arguments to attach and
	thread_alive.
