From 1fdcadf9b2a8c9e191208d32583cd117dace7f09 Mon Sep 17 00:00:00 2001 From: ngie Date: Mon, 22 Apr 2019 18:38:54 +0000 Subject: [PATCH] Rework CXXSTD setting via r345708 This change allows the user to once again override the C++ standard, restoring high-level pre-r345708 behavior. This also unbreaks building lib/ofed/libibnetdisc/Makefile with a non-C++11 capable compiler, e.g., g++ 4.2.1, as the library supported being built with older C++ standards.
