From 3b437400d90fb89ce5e0d74fd79bda9028f185fb Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Mon, 27 May 2019 14:40:25 +0200 Subject: Configure: Remove extra warning and sanitizer options from CXXFLAGS We add the extra warning and sanitizer options to check our code, which is entirely in C. We support C++ compilers uniquely for the sake of certain external test suites, and those projects can probably sanitize their own code themselves.
