- Log ----------------------------------------------------------------- commit 27a3be20a543fdd44517b898421f154e4619c78a Author: Richard Levitte <levi...@openssl.org> Date: Mon May 27 14:40:25 2019 +0200 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.
