If you can change build systems flags easily, without thought, very quickly. Do you still think Werror is a bad idea? Assuming your answer to that is the same as mine. If you always have a build system where you can change flags easily, without thought very quickly, you do use Werror. We frequently (always?) don't have such a build system and we're used to that. We're prisoners of it. It sucks. C build systems are utterly terrible. We're captured by them. Whether it's autotools, cmake, scons, a bajillion make files used directly or whatever. I think acknowledging it is reasonable. I think claiming they are other than terrible is stockholm syndrome. (Note that they may not be capable of being improved, there may be nothing better, etc etc. - I make no claims about it). Not using a flag because it makes life hard when the compiler is upgraded and the flag needs to be changed is a build system issue. Really.
