That flag is _really_ risky over time, are you _SURE_ that all new
versions of clang and gcc will never produce any warnings?  People work
to fix up build warnings quite quickly for new compilers, you shouldn't
prevent the code from being built at all just for that, right?


That would also need Werror, to have warnings treated as errors and prevent building the codebase. If it's about something more, just let me know.

Would this apply to the samples directory as well, no?

I could remove the Wall flags and keep it for development validation purposes on my side to solve at least the warnings that would further see.

Thanks,
Andra
