	* configure.ac <--with-system-readline> (for readline_echoing_p):
	Remove the test.
	* tui/tui-io.c (tui_old_readline_echoing_p): Rename to ...
	(tui_old_rl_echoing_p): ... here.
	(tui_setup_io): Rename extern declaration readline_echoing_p to
	_rl_echoing_p.  Adjust assignments for the both renames.

gdb/doc/
