Modified files:
	gdb            : ChangeLog lin-lwp.c 
	gdb/config/i386: nm-linux.h 

Log message:
	Fix attaching to cloned processes.  This fixes PR gdb/61.
	* lin-lwp.c (struct lwp_info): Add new member `cloned'.
	(is_cloned) Removed.
	(lin_lwp_attach_lwp): Don't call stop_wait_callback.  Instead call
	waitpid explicitly.  Mark the LWP as cloned if waitpid fails and
	retry with __WCLONE flag.
	(lin_lwp_attach): Likewise.  Warn if attaching to a cloned process.
	(detach_callback): Replace use of is_cloned with explicit check on
	LWP id and process id.
	(stop_wait_callback): Replace use of is_cloned with check if LWP
	is marked as cloned.
	[CHILD_WAIT] (child_wait): New function.
	(lin_lwp_wait): Replace use of is_cloned with check if LWP is
	marked as cloned.  Mark newly detected LWPs as cloned if detected
	by waitpid with __WCLONE flag.
	(kill_wait_callback): Replace use of is_cloned with check if LWP
	is marked as cloned.
	* config/i386/nm-linux.h (struct target_waitstatus): Add forward
	declaration.
	(child_wait): Add prototype.
	(CHILD_WAIT): Define.
