If code compiles warning-free, then enabling -Werror prevents
regressions that would add a new warning. Getting code warning-free,
and deciding what set of warnings to be warning-free on, is a harder
task, but using -Werror DOES make sense for projects that are already
clean for a given set of warnings.
