Hi,

I'm also addressing the mailing list now, because i think the last bit
is interesting to more people.

Sorry, my compiler was too old and it didnt produce this warning thus
i didnt notice it.
I think fixed it in my branch, so you can
git pull
make
to try again with the fix.
If there are other warnings that get in the way, you can
disable -Werror with
make WARNERROR=no

and send me all the warnings it produced so i can fix them all.
Thanks a lot for reporting this :)
