Hardly any Cygwin packages require ncurses. Specifically, only aspell,
clear, fvwm, rxvt-unicode-common, singular-base and w3m require it
(according to my most recent setup.ini, which is rather old).

ncurses requires libncurses8:

	@ ncurses
	sdesc: "Libraries for terminal handling (main package)"
	ldesc: "The curses library routines are a terminal-independent method
	of updating character screens with reasonalble optimization. The
	ncurses (new curses) library is a freely distributable replacement
	for the discontinued 4.4BSD classic curses library.  This package
	contains the documentation and utility programs."
	category: Base Libs
	requires: cygwin libncurses8 terminfo

It probably gets updated with each new ncurses release, so that it
always requires the most recent version of libncurses.

Assuming that is the case, GRASS' setup.ini should explicitly list
both ncurses and libncurses8.
