88 dnl
89 dnl Searches for a readline compatible library. If found, defines
90 dnl `HAVE_LIBREADLINE'. If the found library has the `add_history'
91 dnl function, sets also `HAVE_READLINE_HISTORY'. Also checks for the
92 dnl locations of the necessary include files and sets `HAVE_READLINE_H'
93 dnl or `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or
94 dnl 'HAVE_HISTORY_H' if the corresponding include files exists.
95 dnl
96 dnl The libraries that may be readline compatible are `libedit',
97 dnl `libeditline' and `libreadline'. Sometimes we need to link a termcap
98 dnl library for readline to work, this macro tests these cases too by
99 dnl trying to link with `libtermcap', `libcurses' or `libncurses' before
100 dnl giving up.
