Sure, I've committed a change which fixes this warning, as well as the one
you've reported in the other email. Thanks!

I understand, since I use -Werror on my production project too.

I think -Wall are in compiler's option already, but they are not shown in
the regression tests results. It's really not good -- I had no idea the two
warning you've reported are there, for example. So it would be nice to have
warnings shown in the tables. Unfortunately, I don't know how to easily do
it.
