There isn't really a single coherent "C/C++ ecosystem", but for your average "build with make" program there isn't really a 'production' vs 'development' build

There isn't really a single coherent "C/C++ ecosystem", but for your average "build with make" program there isn't really a 'production' vs 'development' build distinction that would be easy to hang this off. (QEMU enables -Werror for builds from a git tree but we had to put a bit of special purpose in our configure script to do that.) You can't tie it to "is this a debug build" because some warnings only appear for optimised builds so ideally you want to have the check for both debug and optimised.
