Having -Werror by default is a no go as you cannot control/predict the
set of warnings (and the quality of those) of all previous and future
gcc/clang versions.

Always using this flag will cause distributions to hate us.

Adding a test (with patchwork integration!) that ensures each commit
posted on this mailing-list compiles without new warning with a chosen
toolchain (and even passes distcheck!) would be nice.
