-Werror is fine for developers, but for distros it's a huge pain.

With every new version of GCC, not only does the set of warnings on by
default change but also its ability to detect warnings (i.e., the same
-Wflag is now more effective). Upgrading GCC already causes lots of
churn, and having to immediately deal with -Werror fall out just makes
this more difficult.
