commit 27a3be20a543fdd44517b898421f154e4619c78a

    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.
