Hi Pedro, If there are specific issues with specific submodules, I would prefer that we disable only the specific subset of warnings that are triggered by that one project. Disabling all warnings as errors may hide way too much.
The INF file for building a lib that uses submodule content can append CC_FLAGS with specific warning disable. We did this approach for the Python3 work in edk2-libc. I think we ran into issue around MIN() macro as well, but I can’t recall exactly how we fixed it.

That may make it impossible to undefine MIN, unless it comes from one of our headers in edk2 proper. We also have similar build warning-as-errors with the brotli submodule(s) which have been breaking the build for recent GCC compilers, for months now. I suggest we find a good way to fix these submodule Werrors for once and for all. Maybe having a project-wide policy of disabling Werror in external (submodule) code isn't such a bad idea?
