From d5c31a1ccfa1195cff160bbad995c68037180570 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Fri, 4 Aug 2006 23:43:59 +0200 Subject: [PATCH] autoconf: Unset NO_STH and NEED_STH when it is detected not needed When configure detects some NO_XXX or NEEDS_XXX is unneeded, unset this variable (actually set it to empty string). This allow autodetection to override the default set in Makefile.
