-dnl
-dnl Check for libreadline and if it is available, check if it
-dnl depends on libcurses. (Normally, it silently resolves the
-dnl following symbols from libtermcap:
-dnl   tgetnum, tgoto, tgetflag, tputs, tgetent, BC, PC, UP
-dnl On RedHat 7.0 however, libtermcap is broken: It contains no
-dnl symbols at all. Fortunately, libcurses provides the same
-dnl and therefore we have to check for that special case.)
