dnl CF_CFG_DEFAULTS version: 13 updated: 2021/01/01 16:53:59
dnl ---------------
dnl Determine the default configuration into which we'll install ncurses.  This
dnl can be overridden by the user's command-line options.  There's two items to
dnl look for:
dnl	1. the prefix (e.g., /usr)
dnl	2. the header files (e.g., /usr/include/ncurses)
dnl We'll look for a previous installation of ncurses and use the same defaults.
dnl
dnl We don't use AC_PREFIX_DEFAULT, because it gets evaluated too soon, and
dnl we don't use AC_PREFIX_PROGRAM, because we cannot distinguish ncurses's
dnl programs from a vendor's.
