dnl
dnl Detect SysV compatible curses, such as ncurses.
dnl
dnl Defines HAVE_CURSES_H or HAVE_NCURSES_H if curses is found.
dnl CURSES_LIB is also set with the required libary, but is not
dnl appended to LIBS automatically. If no working curses libary is
dnl found CURSES_LIB will be left blank.
dnl
dnl This macro adds the option "--with-ncurses" to configure which can
dnl force the use of ncurses or nothing at all.
