Thanks.

While I'm very much in favour of using -Werror for testing
and these kind of patches are great, I think that -Werror
by default is rather silly. We can't control what will be
a warning in the future and sometimes fixing warnings isn't
appropriate - for instance there are warnings in fs2dt.c at
the moment, that is currently considered an upstream problem.

In short, this patch is great. But I plan to also remove -Werror
as the default now that its been brought to my attention.
