If it helps, there was a package I tried to install some time ago that refused
to install until I hacked the Makefiles to remove -Werror. The coders hadn't
anticipated the new warnings added with gcc 4.
Since the gcc devs will only keep adding warnings (and why not ;), I would say
that no release tarball should contain -Werror. It may be useful during
development but it would be unnecessarily painful for release.
