dnl This is a simple configuration-script for the ncurses test programs that
dnl allows the test-directory to be separately configured against a reference
dnl system (i.e., sysvr4 curses)
dnl
dnl If you're configuring ncurses, you shouldn't need to use this script.
dnl It's only for testing purposes.
dnl
dnl See http://invisible-island.net/autoconf/ for additional information.
