From 7b55279d1d856c9ef19d942c2672a3d616254452 Mon Sep 17 00:00:00 2001 From: Ludwig Nussel Date: Tue, 24 Mar 2015 13:25:17 +0100 Subject: configure: --with-ca-fallback: use built-in TLS CA fallback When trying to verify a peer without having any root CA certificates set, this makes libcurl use the TLS library's built in default as fallback.
