It works fine for me. If I add the line:

    fprintf(stderr, "LINES = %d, COLS = %d\n", LINES, COLS);

to Init_curses() in dig_curses.c, it prints:

	LINES = 24, COLS = 80

Note that v.digit doesn't initialise curses until after you have
selected a digitiser, selected a map, and filled in the information
screen for the map.

The variables are set by curses and, as such, aren't valid until
curses has been initialised (by initscr(), which is called from
V_init()).
