6# Add a set of useful warning flags and enable -Werror for CI to prevent
7# trivial mistakes from creeping in. We have to do this piecemeal as we reject
8# any patch that isn't warning clean, so turning on -Wall -Wextra (or W=1) we
9# need to filter out dubious warnings.  Still it is our interest
10# to keep running locally with W=1 C=1 until we are completely clean.

12# Note the danger in using -Wall -Wextra is that when CI updates gcc we
13# will most likely get a sudden build breakage... Hopefully we will fix
