ok.

checking for keypad in -lncurses... yes

-> nothing

nm -D dist.i686-pc-linux-gnu/etc/bin/inter/v.digit  | grep keypad

To be sure I have recompiled set_data:

nm -D dist.i686-pc-linux-gnu/etc/set_data | grep keypad
-> again nothing

grep ncurses src/CMD/head/head.i686-pc-linux-gnu
CURSES              = -lncurses $(COMPATLIB)

locate libncurses

nm -D /usr/lib/libncurses.so | grep keypad
00028b70 T _nc_keypad
00028920 T keypad

Layman's summary:
It seems that the symbol is present, detected, but not used in GRASS although
defined in config.h.
