Everything you say is true. > Has anyone ever looked at setting up something like this before? I did think of a build farm, but it seemed a steeper suggestion than the -Wno-error=... flags. Building and operating a continuous integration infrastructure cost time and money. We don't even have an upstream bug tracker (one that anyone cares about anyway). I'll also note that external, open source contributors are at a distinct disadvantage here. Proprietary downstreams don't release their changes, so they don't have to care about any other compilers. Internal open source contributors @ Intel have access to MSVC compilers, plus they can immediately commit and push warning suppressions when they find out about them, without going through the motions for the nth time.
