Also checks for the dnl locations of the necessary include files and sets `HAVE_READLINE_H' dnl or `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or dnl 'HAVE_HISTORY_H' if the corresponding include files exists. dnl dnl The libraries that may be readline compatible are `libedit', dnl `libeditline' and `libreadline'.
