Tested running ./configure and 'make' using gcc-4.3.8, gcc-8.3.1 and clang-5.0.1. With patch applied, everything works as expected and no unexpected halts during these two steps. Without this patch, clang-5.0.1 spits out lots of warnings related to -Wno-stringop-truncation. Acked-By: David Sommerseth <dav...@openvpn.net> -- kind regards, David Sommerseth OpenVPN Inc
