From ae215b14bdbd459afe5f371175765fae817062a8 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 8 Jan 2006 18:39:44 +0100 Subject: kconfig: factor out ncurses check in a shell script Cleaning up the lxdialog Makefile by factoring out the ncurses compatibility checks. This made the checks much more obvious and easier to extend.
